Use our measurement guide. Details When it comes to chastity I often like to keep things simple. One cage, one ring. Easy, right? It makes putting the kit onto someone (or yourself) a painless procedure leaving much more time to tease and torment you. This S171 cage comes in two different sizes and has a nice discreet downward angle meaning you can wear it comfortably and privately. However, that discretion will be a thing of the past once I get my newly manicured and pointed nails between the steel bars. Feedback is important and I have a strong suspicion that you'll willingly provide it as I squeeze your locked balls between my nimble fingers. The hinged back ring opens easily making it very straightforward to put on or, less commonly, take off. If you encounter any issues with the placement of the hinge we recommend covering it with a padded plaster, some plastic tubing or a soft strip from a nylon stocking for a more comfortable experience. Included in the box 1 stainless steel cage 1 steel hinged ring - 40mm, 45mm, 50mm or 55mm inner diameter 1 sliding lock with 2 keys Optional Extras Compatible back ring - Hinged - Available in 4 different sizes Struggling to keep it up (so to speak)? You might want to consider wearing your cage with a waist strap as that will help to balance the weight and keep everything where it should be.
