Review on Enhance Crafts and Décor with Gartful 2790 pcs Clear Self Adhesive Rhinestone Stickers - Round Gem Sticker for Scrapbooking, DIY, Wedding, and More! by Dawn Fischer

They are supposed to be self-adhesive and although they have some kind of glue on the back it is cheap. You are not attached to anything. You can touch one and it will fall. Luckily I have masking tape so I used that to attach them to my project. Also, I wasn't a fan of "pure" colors. These defs look cheap. You can see the silver metal backing through the crystal and it looks pop. I have real "clear" crystals and they add that extra sparkle to any project. It is in order. Keep in mind that self-adhesive are cheap and don't last long and aren't very transparent. Purchase at your own risk.
