I love snap buttons. Collect as many as you desire and then change out the look of your bracelet or earrings whenever you wish! Just snap the button out and snap in another! It's simple and so much fun!
 
The wonderful thing about snap buttons is that most of them aren't just flat. They're dimensional!  Long purple sparklies with a couple of crystal sparklies thrown in make up this wonderful snap button!
