Chastity device discussions and reviews discussion

Hello all! This is my very first contribution; before now, I was just a silent observer. But let’s get to the point. I was browsing dhgate looking for fresh designs and came across something interesting: a new A-ring design. rBVaI1kSiUmAcQFcAAG1UIG2DC8157.jpg It’s an anatomical type with a snap mechanism. The most intriguing part is the lock, which sits hidden inside the ring itself. This makes the entire design much more discreet. In Chinese, they refer to this as “open mouth”. My question is: has any well-known manufacturer adopted this design, or did China invent it? Has anyone here had experience with it? Here’s another picture of a cage paired with this ring: rBVaI1ktO4OAfYyEAAaarJxZsuo470.jpg Apologies for my poor English.
