Description

BE ASSURED A PERFECT FIT

Our 3D printed Sizing Rings are the same sizes as our heavy metal rings, fully functional, and will help you discover your perfect fit prior to investing in a lifetime accessory. We print them in-house with body safe, biodegradable PLA plastic (color shades vary) and the cock rings have a proprietary engineered breakaway feature – for the safest sizing experience possible. Our size range is adequate for about 95% of men but you may choose to verify you are in range with our Sizing Guide.

LESS THAN FREE!

The complete Sizing Rings Kit is a bargain at $49.95 but it ALSO comes with a $75 Discount Code for future use – we give back 150%! The code is valid for 6 months and can be used to purchase any regularly priced metal ring. Discount cannot be combined with other offers or discount codes, minimum purchase is $100.

INCLUDED IN THE SIZING RINGS KIT
  • Cock Rings: 8 sizes, 44-58mm
  • Glans Rings: 6 sizes, 22-32mm
  • Teeny Tiny (finger) Ring Sizing Tool
  • Printed Sizing Guide and other information
  • Small piece of sandpaper, just in case
HOW DO THEY COMPARE TO METAL?
  • Cock Sizing Rings: Band width and thickness are the same as our standard metal cock rings but not quite as thick as GOLIATH.
  • Glans Sizing Rings: Band width is 12.5mm – midway between our Slim (10mm) and Wide (15mm) styles – and thickness is the same as all our metal glans rings.
  • Fit and Feel: Plastic is a poor proxy for the heft of metal when worn casually but our sizing rings perform exactly like our metal rings during playtime. The printed Sizing Guide has step by step instructions – more than you will find on this website – to eliminate all the guess work in finding the one best size for full time wear.
FREE SHIPPING

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

SIZING GUIDE

Included in each kit, our printed Sizing Guide contains more helpful information than you will find on this website. Its contents are proprietary and developed over years of coaching gentlemen through the fitting process.

EVEN MORE SIZES

Sizes 42mm, and 64mm are available on request, just leave a note at checkout. Note that we will swap out ring(s) on the opposite end of our size range so you will always receive exactly 15 rings total.

Alternatives

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.

    glad I ordered

    I was about to submit an order based on previous measurements when I decided I should order the sizing rings just to be sure. It was “risk free” in that I’d receive a discount code for a future purchase that was larger than the price of the sizing rings. Glad I ordered them! I wound up ordering the final products in slightly different sizes than my earlier measurements suggested, and the final fit is *perfect*.

    Easy

    The sizing rings makes the whole process smooth. I tested several of the sizes before I made a decision and it took all the guess work out of sizing. If you’re planning to buy a King Ring it’s foolish not buy these first. The coupon by itself makes it worth it.

    Best way to get the right size.

    If you already plan to purchase a ring, these fitting rings are a must to ensure the fit you want. I tried printing them myself with my own 3D printer but I could not match the quality of these.

    Sizing Rings

    I purchased the sizing rings specifically for the glans sizes. I put on the 24mm ring and wore it around for a while. FYI, I am a grower not a shower and when my penis is soft all the excess skin gathers behind the head. The pressure of the excess skin would cause the 24mm ring to slip off. I contacted Kings Rings and the immediately sent out a 22mm sizing ring at no extra charge. Outstanding customer service. The 22mm is the correct size. These sizing rings take all the measuring and guess work out of ordering the correct size. Plus, you can wear it around to make absolutely sure. Great easy to use product.

    Deliver fault

    Got the sizing kit in today. The package seemed to be a little rough. Opening it the biggest size 58mm was broken, the rest were all good in shape. Even tho I think the 58mm would be a little to big for me just disappointing. Now I’m blaming the handling 100%, it’s not that heavy and it sounds like legos.

    True

    These are true, I bought the set and tried on multiple. The sizing guide is on point. Follow it for help, or email for assistance. Weight of the true rings is different!

    A must buy before purchasing a ring

    Take the time to buy this sizing kit first. It will be of great aid in the purchase of your ring because it takes all the guess work out of proper sizing. Comes with a coupon code that applies to purchase of the actual ring you select. This makes the satisfaction difference and it a brilliant idea.

    A must

    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.
