Waist straps are a fan favorite in the chastity world! New for 2025, the KINK3D Strap Ring with integrated loops is designed specially for a waist strap.
Some people find that when their chastity cage is worn unsupported, it can hang down away from the body. Wearing a strap can help the cage sit in a cozier position, enhancing the overall snugness and stability of your loadout. This reduces the chance of ball slips while minimizing the temptation to pull out.
The two loops built into our Strap Rings are approximately 28mm x 8mm (1.1" x 0.3"). They're compatible with Mr. S Leather Neoprene Waist Straps, as well as straps from many other makers, plus DIY creations.
This product includes a Strap Ring only. For a complete chastity device, you will also need a cage piece and a lock (sold separately). And since you're getting this ring, you'll probably want a strap too!
Standard Rings: 8mm thick. These work for most people.
XD Rings: Extend forward by an extra 2.5mm. This tightens the ball gap, and also makes the rings more rigid. Good for people with smaller balls to prevent escape.
Curved Rings: 5mm backward curve at the bottom. Can be helpful for solving pressure under the scrotum or painful squeezing of the testicles.
Note: Curved Rings increase the ball gap, making it much more likely to accidentally slip out. Only get a Curved ring if you really need it.
We recommend starting with the Standard ring style, unless you already know from past experience that you need a different shape.

Arctic White
New for 2025, KINK3D Arctic White is 3D printed in the US from dye-free, high-density PA12 nylon, using advanced machines developed for the biomedical industry. These rings are finished with the same vapor solvent as our classic black products, giving them a satin-smooth, nonporous surface.
Arctic White pieces may contain ultra-thin filaments embedded beneath the surface. These can appear as fine strands or miniature colored spots and give each piece a unique signature.
