GIF IMAGE, to understand better how it fits together Does anyone have this chastity cage from Ali? Interesting design however i'm afraid it might be pinching behind the balls.
This is interesting- an evolution on a non detachable (ball sack retainer anyway) metal version -both of which are similar to the "BertBea" device with pop rivets posted on this site a few years ago and again recently.
Using the title as a search brings this link - https://www.aliexpress.com/i/3256804382064781.html?gatewayAdapt=4itemAdapt , also seeing it on Ebay from various sellers
https://www.aliexpress.com/item/1005004262673983.html There a similar chinese metal device here... but the ring that goes behing the ball looks very tight, so i wouldn't buy it. The plastic one looks more comfortable maybe i'll give it a try. It's available by multiple sellers, shipping cost varies. Also the white one is cheaper than pink or black.
There was a thread about the metal version of this a few months back: https://www.chastitymansion.com/forums/index.php?threads/blast-from-the-past.46151/
