Birdlocked Mini 45mm for sale.

Hello all, I'm switching over from a Birdlocked mini to a Exobelt Extreme and I'll have no use for it. It's the clear, 45mm type. The only thing wrong with it is that while trying to make it work with my specific anatomy I used some zip ties to go around the base of the head. There are two little nicks in the silicone that are purely cosmetic inflicted while trying to get off an over tightened zip tie. It is in no jeopardy of tearing nor do the nicks go deep.

Ideally I would like to get 80 USD including shipping but it's negotiable.
