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

I love it, i wont' lose my pins, just make sure the pin is facing the direction you want when you tighten it, lol . there were a few defective ones, so you don't get a full 30, so I'd expect a better vetting job of defects, but nothing to lose my mind over. I probably got close to 23 good ones to use. I'm very happy with how well they work. It makes me nervous that I could lose the allen key but I LOVE that they give me 3 allen keys! more security lol. This is a great product, Im' glad they make something like this.
