Not Sturdy

The pins came out so cute... BUT, they're not sturdy whatsoever. I've tried placing several pins on my backpack, and a few days later they've completely come off the backing. The glue holding the pin and the backing is not very strong, especially since the keychains are made of slick acrylic they tend to fall of easily. These are good for a one time use (like on your shirt, as long as you don't touch them). Other than that, not very good.
