Works great!!!

### ⭐⭐⭐⭐⭐ No more backs coming off!
*by N***E on February 19, 2026*

Finally the backs of my pins aren’t falling off. I am a teacher and we have pins for years of service plus personal pins on our lanyards. At least once a month, one of the backs falls off and I have to deal with a piece of eraser instead. These fit perfectly and do not come off until you squeeze the prongs. Love it!
