DO IT YOURSELF
Download the 3D models and print the rings yourself or with the help of a local print shop. If you live outside the U.S. this could be a good option, ask us about our DIY discount when you come back for a metal ring in your preferred size.
GET A SINGLE RING AT CHECKOUT
You also have the option to add a single Sizing Ring to any metal ring order during checkout. This will allow you to verify your ordered size before unsealing the high value ring (see our Returns Policy) but what you don’t get is the opportunity to compare different sizes. We offer this option but do not recommend it.
You're gonna put a lot of money into your precious jewels, make sure they fit right! With the added bonus of a discount on whatever ring you choose!
Do yourself a favor and get the sizing rings
These are a must!! I was able to comfortably order a size smaller than I thought due to being able to practice with the plastic to get comfortable with a perfect fitting ring. And the discount you get when you order the sizing rings makes it a no brainer.
Gentlemen- do yourselves a favor and get the sizing rings. You won’t regret it. Take your time testing them in real world scenarios and go snug to avoid slippage. The real things are a lot heavier. Cheers!
Great assortment of sizes!
Love the variety of sizes available. Small increments make it easy to size up/down. Give each ring a day of wear to find your best size!
It's not rocket science
If you’re new ro wearing member rings this is worth the investment if you’re planning on buying rings of any sort. Yeah it’s they’re just 3d printed PLA rings but the discount more than makes up for it. That’s at least 30-40% off of a glans ring at least so….. Sizing rings plus a gift card is a pretty good gift.*wink, wink
I definitely recommend these!
These are well made and a really good way to determine which size is best for you. And if you buy them for $50, you get $75 off your first order. That’s a really good deal. For me, I figured out 3 sizes that I thought would be good and it was great to have the opportunity to see how they fit and felt flaccid and erect to narrow my choice down to the exact right size that was perfect for me so I knew what to order. I highly recommend getting these.
The base rings given were perfect for running a trial by fire on various ring sizes. I would definitely recommend following the included instructions and slowly size down. I realized my base is larger than I thought during the process! The included $50 coupon incentive (more than the cost of the size rings!) really just goes to show Scott’s commitment to providing a quality product. If you are remotely interested in any of the rings in the catalogue, this is definitely the place to start the journey!
The sizing rings work great, I went for the full set and even though it turns out a glans ring was no option for me, it did give me the option with this measuring set to check for a nice “shaft” ring instead!
I stole Konrad F’s idea and will use this set when I go swimming so I do not have to worry about damaging the brand new c-ring
We are glad you had success with your sizing rings and were also enabled to experiment with an unexpected use. The sizing rings are water proof, float very well, and can be a fun toy in the pool, sea, or lake. We recommend rinsing them with fresh water after and drying before storage – same as our metal rings. On that note, only our gold plated rings are vulnerable to tarnish in chlorinated or marine water (same as all gold). You can confidently wear all of our other rings while swimming or soaking.
These sizing rings were fantastic in allowing me to dial in my Goldilocks fit. I wanted to find the size that would allow me to wear a ring all day but still get good constriction when hard. The added discount code made this a no brainer purchase!
These are a great value and they’re good for first time users of cock/ glan rings compared to the cheap rubber band ones. That don’t really work for a daily driver type of rings.
Now I’m wondering if the metal ones grip my member better than these?
Our plastic sizing rings are perfect for assessing the physical fit of our metal rings and exploring the comfort of a wide band. However, they are a poor proxy for the experience of wearing a heavy Tungsten Carbide ring all day. Our printed Sizing Guide (included with your Sizing Rings) suggests you should identify which ring size is too small and then purchase one size larger. This is the best way to determine which size is most appropriate for use in both contexts; casual and playtime.
I have never worn a ring before so very glad I decided to start with the sizing rings. They are amazing for getting used to the thickness and the feeling of wearing a ring. The only thing I personally would suggest is that once you find one that is comfortable, see if you can fit in the smaller size and still be comfy hard as when I gave them to a friend to try he chose a size and wished he had gone one smaller when he purchased an actual king ring because the weight made a big difference. Being small when soft I thought the 52 was best but once he told me that I tried the 50 and was still able to have an amazing release so ordered a 50 and have to agree with the weight it stays in place better being a size smaller.
These were very helpful to me in the decision making process of which C-ring to buy. I have worn cheap metal and stretchy c-rings before. The metal rings were all too small and painfully tight. The stretchy ones pinched and were too elastic to constrict blood flow during sex. I would recommend anyone considering purchasing one of King Ring’s metal rings purchase a set of sizing rings, even if you’ve worn C-rings before and think you know your size. For one thing, these are less than free with the generous coupon which you will receive. Secondly, I found that the experience of wearing a 20mm wide ring vastly different from the narrow, cheap, metal rings. In my experience, the extra width added to the comfort of wearing the ring for extended periods and improved constriction when erect.
I ordered a 50-58mm set of sizing rings and Scott was kind enough to throw in a 64mm ring as well. Dealing with Scott was an absolute pleasure. He answered my questions amazingly quickly and was very helpful. He really wants you to be happy with the “real” ring you eventually purchase and confident that it will be the correct size.
Wearing these sizing rings will make you even more eager to get one of King Ring’s gorgeous creations.
These were perfect for learning how to put on a ring. I was so glad I ordered a set. It got me acclimated to wearing a ring with such an awesome thickness – after a few days of all day wear, I almost forgot I had one on during the work day. I also now know that there are three sizes I can comfortably wear, and which of these three is my ideal Goldilocks fit. Customer service was great, and Scott checked in a few days after delivery to see how the fit was and to let me know he was available for any questions about sizing and fit. And it promptly came with a coupon for my final King Ring order!
I’m so glad that King Rings offer the sizing rings. Me and my husband have both worn cock rings but nothing with this thickness before. It’s awesome! we both found our size and wearing the daily and trying on the different sizes to find out perfect match. We’re both still deciding on what ring we want to purchase as our “daily driver.” Hoping to pick up two soon! Thank you Scott!
