Welcome Yng engineer!
Making chastity belts is not as easy as it looks, To many opposing forces and to many sharp edges.Not to mention body forms that vary in every direction and on a daily weekley basis

Chastity belt rip offs mmmm I guess belts have been around a long time but most manufacturers dont build in big numbers as there is only a small client base [People who admit to liking belts] as opposed to people who have a fantasy involving belts.
We look forward to hearing more about your belts maybe you will bring some competitive designs to this world. Do post us some nice pictures when you have a viable device
