Review on 30Pcs EuTengHao 9X5.5Mm Silver Pin Keepers Locking Pin Backs Clasp Lock by Dustin Ramsey

I didn't know these existed until I asked how others secured their pins and was recommended these!I've had pins stolen off my backpack while at events; majority of them are kids/teens while their parents watch them steal! I lost one of my favorite pins this way, and they're very hard to replace since they're from indie artists I get from conventions. Anyway, once I replaced the backings with these and gave my pins a good tug (like, hard enough where you'd feel someone jerking your bag) they held on tight and I'm so impressed!Yeah, they take a bit of patience to put together since the black screw doesn't come already set in the silver tube, but with some patience, it's pretty easy to figure out! If the tube doesn't grab onto the pins point, flip it around (in the image, it shows the concave part out, I had to flip it around so the flat part was facing outwards) and screw it on firmly.I am super ready for more indie artists and Disney pins now, and I don't have to worry about my pins getting caught and being pulled off, or kids/teens stealing them as I wait in lines!
