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 22mm, 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 14 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.

    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.

    Sizing rings

    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!
