Description

Be assured of a perfect fit! Our 3D printed Sizing Rings are the same dimensions as our heavy metal rings and will help you discover your perfect fit prior to investing in a lifetime accessory. We print them with body safe, biodegradable PLA plastic and color shades vary. Our size range is adequate for about 95% of men but it is recommended you verify you are in range with our Sizing Guide.

– Glans Ring Set; 5 sizes, 24-32mm
– Finger Ring Sizing Tool

Sizing Guide: Included with every kit, this printed brochure contains more helpful information than you will find on this site. Its contents are proprietary and developed over years of coaching gentlemen through the fitting process.

Less Than FREE – Each set of rings comes with a Discount Code worth $50 or $60! The code is valid for 6 months, can be used to buy any regularly priced metal ring, and cannot be combined with other offers or discount codes.

Free Shipping: No cost USPS First Class shipping to U.S. addresses. International shipping is discounted, see prices during checkout.

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.

    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!

    A unique offering and excellent first step towards choosing a King Ring. Great for practicing how to put on and take off a ring, especially for the newbies. Also helpful in understanding how a ring of this thickness will feel worn for long periods of time under clothing, with or without underwear, and also during arousal and release. A smart purchase before deciding on a metal ring.

    I bought these to make sure I was getting the correct size. They are light weight and comfortable to use. After finding my size I think I could even use these while swimming in a chlorinated pool so I won’t have to worry about damaging my good one. Included is some fine sandpaper to smooth out any rough edges – thoughtful touch.
