I think this is a copy of the Custom Chastity Saint. I'm intrigued by the double A ring I think there are also copies of the Ghost in sizes Small and Regular Anyone ? https://www.aliexpress.com/item/Lat...ba-43fa-b6e4-9f31d50d2b12&transAbTest=ae803_5
It's worth noting that it's not a very good copy - the trench arrangement is supposed to be a track for a piercing anchor. Also the more recent Saints have swept back head section to ameliorate turtling.
