Review on 🧷 120-Piece Pin Locks Pin Backs Locking Clasp Set with Wrench - Cooyeah Locking Pin Keepers Backs Locking Clasp Sliver, 6 x 5 mm by Doris Tran

Price compared to many options here at Revain and this was the best value. Quality doesn't matter as they are very durable and well made to do what they are supposed to do. A little tricky and slow at first, but eventually you'll get the hang of it and you'll be able to put them on much faster. I found it easier insert one screw at a time and turn them just a few turns, then slide them over the back of the pen and tighten. The key is already partially threaded so you don't try to adjust it once you put the pen down if that makes sense. Will definitely be using them again once I'm done attaching that first set of pins.
