These are a must have for anyone with pins. They're cheap, strong, and easy to use. They lock well and I've never had one pop off, even after being run through the wash.

If these really work, they are the most epic find! I've got a stellar Disney pin collection that I now have on display on my backpack. I've been fearful of showing off the collection because of unsecured backs that allow the pins to loosen and fall off. I think these are the answer, but I'm reserving that 5th star for the trial run when I take my pin-filled backpack out for a day in Magic Kingdom!

They lock well and are not difficult to unlock with the correct technique.

I bought these because : off Shein, You can get a lot of really cute pins but if you just use the backing, they came with you’ll end up losing 50% of in a matter of time. These locking backs have worked very well for me, and I have given some away as some of my coworkers put pins in their badges. Since some of the pins are a bit sentimental it’s nice knowing they’re safe with these backings.

They work well for locking- I put a lot of enamel pins on a work bag and I'm always afraid I'm going to lose them. It takes a little skill to remove them, you have to hold the pin down and pull up on lock. They are easy to use & don't seem to add too much weight

I like this pin clasp so far. I made it a day without worrying about my pin falling off
