I have a small fortune invested in Disney Pins and the backs they supply almost seem intentionally designed for your pin to fall off. This is a MUST for any pin collector who wants to walk around with their pins. They are just small enough to not be a burden. I might should have opted for a black color but these are perfect!!!

These are amazing. We gave these to all of our girl scouts for there pins. We always have pins falling off there vest. With these they don't. They do what it says Lock. I recommend these to anyone that is purchasing them for pin back falling off.

I used these backers to replace the backings of pins on my daughters girl scout vest. The hold better and have a tighter fit than the original backings.

I have a lot of cool pins that i have on my work lanyard and i usually had the black rubber pins on them and there would always be one pin that would fall off if i hit myself on something and sometimes i would notice that the pin fell, other times unfortunately, i wouldn't. But with the locking pins i feel safer and i hit my lanyard so many times and none of my pins have fallen off. I'm glad i won't be losing any pins anymore :) i plan on buying more locking pins of course so all my pins will be safe.

These are great pin backs. They work really good for Disney pins,Which is what I'm using them for. To take them off you pull the end and twist it I love them!

I purchased these pin backs for disney pins because the rubber ones do not stay on. These are very secure, a lttle hard to take off but you will not lose any pins with these. Every pin back in package worked perfect!

I collect pins, and I like to display some on my purse, jacket, or even whatever top I am wearing that day, but I don’t trust my pins with regular rubber backs because I don’t want to lose any! These locking pin backs are easy to attach and easy to remove, but they don’t come undone accidentally, which is what I was worried about! I typically need both hands to remove these backs, which means I feel confident my pins are secure. I’ve been using these locking pin backs for several months now, and I haven’t lost any pins! These locking backs are worth the investment, especially since pins can be expensive!

I started collecting enamel pins. Which is great, except most of them come with backs that don't like to stay on with normal movements. I bought these because the set was decently big for my needs and was a very reasonable price. I've had no issues with them, they're easy to put on, and none of my pins have budged. 10/10 would recommend. (Haven't tried to remove them, but I'm given to understand pliers help.)

I like to put pins on my backpack and they take a bit of a beating. I've lost a few pins that can't be replaced, and very nearly lost several others. No more worries since replacing the backs with these locking clasps. Also, several other reviewers complain that the clasps can't be removed, but I have no problem removing them if needed.

I have an ever-growing collection of pins, buttons, patches. Most pins come with horrible little rubber clutches or easily bent aluminum. These locking pin backs are exactly what I needed. They slide on and are easily unlocked when needed. I got two packs of 50 for the best price on Amazon. The pins came in a two reusable, zipper bags of 50 each. There was no shipping waste other than the outer padded envelope.
