Chastity device discussions and reviews discussion

Hello all, Since this is my first time posting, I wanted to take a moment to introduce myself and share the issue I’m facing. I’m Karol from Poland (guy), and I recently convinced my girlfriend to keep me locked up while we play out our contract game. As a total newbie, I figured out the correct ring size for it was 46mm, but I accidentally bought one that is 47mm instead—so it’s a bit too large. Now I’m on the hunt for a smaller ring to fit this same cage. I haven’t spent much yet because I wanted to be careful not to waste money picking the wrong size again… (just like what happened now). I’m wondering if this cage actually comes in 46mm? Do you think a 45mm would work for me? Have you found rings compatible with this cage anywhere other than AliExpress, since shipping takes so long? Your help would be much appreciated! Here is the link to the cage:
