KINK3D On Demand base rings are intended for chastity experts. If you are just getting started with our products, we suggest choosing from our stock base rings, which work well for most people. If you already have experience with our lineup and are still on the hunt for your forever cage, On Demand may help you fine-tune your perfect fit.
All On Demand base rings are printed with a new Airlock notch feature, which makes using the Airlock much easier. This Airlock notch does not affect the standard metal locks, which are still compatible.
Four Styles
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.
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.
NEW! Curved XD Rings: Combine the extra 2.5mm thickness of our XD rings with the 5mm backward bend of our Curved rings.
Curved XD rings have a ball gap between Standard and Curved. You may want to consider the Curved XD style if:
- You like the shape of our Curved rings, but you experience the occasional ball slip.
- You like the surface area and rigidity of our XD rings, but you want less forward pressure on the scrotum.
- You have a favorite ring size (diameter), but the Standard gap is a bit too tight, and the Curved gap is a bit too loose.
More Sizes
On Demand base rings are available in half-size increments. This means you can now dial in your preferred diameter to the 1/16" (1.6mm) level.

Note: On Demand rings that are the same size and style as a stock base ring will be identical to the stock ring, except for the Airlock notch and the location of the size marker. For those configurations, if you don't specifically want the Airlock notch, we suggest ordering the stock ring instead.
