Review on Secure Your Pins With EuTengHao 30 Piece Gold Locking Pin Backs - 9Mmx5.5Mm Keepers by Terry Myers

Really straight forward, they give you everything you need to "lock” your pins, at first it was hard to understand how it worked but once you get it you’ll understand it! I tighten my pins really tight and they didn’t strip or anything.

Had my gf tug on the pins while bag was on back and you’d notice someone taking it before they’ll get off the bag
