    Excellent Quality and Exceptional Service!

    If you are considering a King Ring keep in mind that you are buying a high end piece of jewelry. Compare this to other “metal” rings and it is expensive. When you compare it to the quality of bracelets, necklaces, ect. you are getting very high quality at a fair price. The quality is excellent, the look is great and the weight feels great! It is truly different than other rings on the market.

    As great as the quality is, I would like to focus more on the process. Scott does a wonderful job. Absolutely take advantage of ordering a sizing kit. You get all the sizes so that you make sure to order the correct size. I was concerned because I thought that I was going to need a 60mm and maybe even a 62mm. I emailed Scott, we started off with the sizing kit and although I was nervous 58mm was not too small and not too big. Scott followed up with a email after I ordered the kit and again when it arrived to make sure I wasn’t having issues figuring out the correct size. Once I ordered my first ring, the same thing. I got a confirmation email from Scott that was not automated and again when it was delivered. It was truly and exceptional experience and it gave me confidence that I ordered the correct size. I love my ring and so does my girlfriend. I bought mine purely for atheistic reasons. Scott exceeded my expectations and I anticipate buying more from him in the future. If you are on the edge, I suggest start by ordering the sizing rings, when you finally receive the ring that you pick out, you won’t be disappointed!

    Absolutely Fabulous!

    The feeling I had was confirmed as I lifted the package then unpacked my FOP Midnight. The weight feels incredible in your hands and the quality is unmistakable.
    Thanks to using the sizing rings prior to ordering, it is the perfect size.
    I was able to debut this ring and matching Teeny FOP Midnight at a recent lifestyle nude pool party. It was our first time at the venue and the C-ring definitely drew attention to my package!
    A few people commented on it and one lovely gal asked me all about it.
    I also played for the first time at the party with the actual ring on and it felt even better than the sizing ring because of the weight.
    My primary female partner loves the look of my package in it and said my balls felt great against her with the extra bulge from this ring.
    Highly recommend considering both rings whether as your first or an addition to your collection.

    Thank you King Rings!

    Much love ✌️ 🍍 🌈

    Love it!

    Firstly, the ring is stunning! It’s like a band of northern lights around my bits. The quality is amazing, and it feels incredible just walking around in. It’s snug, weighty, and really comfortable.
    Customer service was great. Scott was quick to reply and super helpful. I bought the sizing rings first and the fit was perfect. Definitely recommend!

    Love it

    This thing is amazing! It feels as good as it looks so smooth and comfortable.
    I would recommend getting the sizing rings and take into consideration the weight of the ring I ended up going 2MM smaller than other rings I have and this fits better.
    you won’t regret picking one of these up

    Excellent quality you won't find elsewhere

    First and foremost get the sizing rings. For the quality of these jewelry items, you want to know exactly the size you need. Second these rings are incredible. The pictures do not do them justice. The weight, the quality of feel, the visual appeal… These simply cannot be experienced in a preview image. I highly recommend King Rings. The FoP Midnight is such an exquisite piece. The abalone inlay contrasted with the black ring are simply stunning. The weight even provides a sense of security. There is an elegance and class with these rings you will not find anywhere else.
    Scott is a gentleman. Very pleasant to communicate with and very understanding. He knows how to treat customers. Don’t believe me? Buy a ring and you will soon realize why King Rings is the king.

    Totally in love with it

    I just bought this ring and fascinated by the sheer weight of it. The sizing rings are nothing compared to this ring has to offer. I got a larger size as per the sizing rings as well as a teeny ring for my finger. To be sure I actually wore the sizing ring for a couple of days and tried the different sizes per the instructions provided.

    I wear it at work and people have not stopped complimenting me on the one they can see. Yes, I am brazen enough to tell them that its part of a set and love the dumb founded looks on their faces. I plan on wearing it as many days as I can and plan on getting a smaller one for those days that I want a little extra pressure down there and tug. I cant wait to be in a position to show it off to show someone the full matching set at once.

    Working on testing out the glans rings too as you can never have too much adornment and stimulation during the day and when the time is right. Definitely looking forward to my next one and alternating days with them.

    This is the one ring to rule them all.

    Forged in masculinity with exquisite attention to detail, this ring will remind you that what you have is not junk, but precious jewels to be loved and appreciated.

    In sunlight, the abalone catches the light and draws attention. The black contrast will make it pop, perfect for the exhibitionist. The weight is incredible. If you have used other light weight rings before, even stainless steel, you will appreciate the difference. Durable and attention grabbing. Easy to clean with no tarnishing.

    I wear one of my now 3 King Rings daily at the gym, yoga, work, store or home, this is quality and something you deserve. As a backyard nudist in a nice warm climate, it is perfect. If I was anywhere near a nude beach… but landlocked here.

    Of the dozens of rings I have, once I got this, the only rival it has for wear time is the KR Fire Dragon (now discontinued). The red is so intense in the sun. The others all now sit unused. Maybe I can use those old ones as napkin rings.

    Sizing; so critical to get right. Get the sizing rings. If you are going to go for all day wear consider a few things in your decision (some I thought of before, some I realized after buying this, my first KR:
    1) The rings are so much heavier than the sizing rings, consider going down by a 2 mm increment from the sizing ring you found that stayed in place all day if looking for more of an all day wear (any staying in place is when hanging free, and not banging the boys all day). If only looking for a boost during activities, the constriction must not be so much that things both hurt and after you finish, keep you in a salute.
    2) Shower or a grower? If a shower, you will likely have it easier to get the right size, since there is likely less circumference variance during the course of the day. Growers, we have a bigger change in the variance it seems. Wear the test ring all day when hanging free, if there is slippage, try the next size down. For me, a 50 mm is good during activities, but during the day slipped off; a 48 was good, but the 46 stayed exactly where I wanted it; but it too restrictive for activities. Side note, I’ve been curious about the variance during the day, and started a little log for measurements for morning, noon, late afternoon, before bed, and when excited. Try it for a week, or every few days and see what you get as an average and a mean for flaccid measurements. Use the excited state measurement for the relative maximum minimum size to be safe and healthy. Use a cloth fabric measuring tape and convert the circumference to diameter, in MM.
    3) For the finger test Scott mentions – how large are your fingers? A thick boned finger could be the equivalent of 2 skinnier fingers (or more).
    4) Are you well hydrated? Crazy sounding, but being dehydrated can reduce overall girth.
    Take your time and use the sizing rings, wear them all day on different days. I did large down to smallest I could get one with room “to grow”, then worked my way up again. When in doubt, Scott responds very quickly to questions and provides excellent customer service.

    Great product, great customer service. I have this in Father of Pearl, two sizes in Fire Dragon and a FOP matching glans ring. Invest in this for yourself. Enjoy it with your partner.

      King Rings

      September 24, 2024

      Please note: King Rings official sizing guidance, printed and included with the Sizing Rings kit, emphasizes performance testing as key to finding your best fit. The Three Finger Rule of Thumb is just a sanity check before things get hard, fingers are a blunt tool and our sizes allow for a fine-tuned fit. You should buy the smallest ring you can wear comfortably while erect. Will that size slip excessively when worn casually? You’ll find out and we can offer tips to mitigate slip but it is your best/only option for a single ring worn both casually and during playtime.

      Assessment via casual wear is ineffective and not part of our sizing guidance because our plastic rings do not mimic the weight of metal. Finding a size in plastic and stepping down a size solely to mitigate anticipated slip could potentially put you into a dangerous situation. Our Sizing Rings let you fully vet every one of our sizes safely, you want one that performs well without robbing you of pleasure. You can expect the exact same result from a metal ring while then also discovering the joy of casual wear.

    A thing of beauty

    I have several cock rings from here, but the Black FOP might be my favorite! The multi-color abalone really stands out against the black, and it looks nice on my paler complexion. I had to get the teeny ring to match and couldn’t be happier with my purchases!

    Functional Art

    I’m 91 years old and never wore a cock ring. After purchasing and wearing your F.O.P. Midnight cock ring and glans ring, I don’t want to take them off. Too beautiful! To say they are exquisite is no exaggeration. Thank you, King Rings, for your functional art.

    Incredible

    I could not be more pleased with the rings I received. The quality of the rings is incredible and I will definitely be a repeat customer. The only person more pleased with ring than me is my partner. They haven’t been able to keep their hands of it since it arrived. If you’re on the fence about it I encourage to take the plunge. You will not regret it.

    Father of Pearl, midnight

    I received my father of Pearl midnight. This would be my fourth ring from King Rings.
    I also have the original father of Pearl. I was a little reluctant to get the same type of design, except in black, but the Albone is beautiful and it gives it a totally different look than the original father of pearl.
    Both of these rings are stunning, and they look wonderful in the sunlight
    I live in an area where you can be nude outside and those are my two prettiest rings
    I have purchased my first ring from King Rings probably going on three years ago and have consistently worn mine and alternated from ring to ring every few days
    I am now on my way to purchase. The black rose.
    I wear my rings, not only throughout the day, but I sleep with them on as well they never come off, except for Cleaning
    Not only does wearing a ring look good, but it definitely increases your sexual stamina no matter whether you’re alone or with a partner

    Keep the designs coming

    Amazingly hefty feel

    Just received my ring today and I could not be happier. It looks sleek, elegant, and regal. I just love how it feels when I put it on that hefty tug when I wear it in public. Chef’s kiss.

    They are very fucking cool.

    I have never really worn a wedding ring since losing two of them. For our 25th anniversary my wife was like, hey let me buy you a new ring, and I replied, only if it comes with a matching cock ring. Then I found this site. Then I ordered the measurement kit. Then I talked to them and said for sure I will order a set, cock and finger. Wife picked this Father of Pearl set. First thing King Rings said to me when the order went in? Wait until you see it in sunlight. The day after getting them, on a patio in the sun, my wife and I were both shocked at how cool it looked in the sunlight (finger ring). From a guy who is not into jewelry, these are fucking cool. I will 100% order another set. Probably the blue ones. Really interesting technology in use because they are beautifully engineered and very comfortable to wear.
