“These stickers arrived in a round tube on flat sheets. The instructions said something about cleaning them to remove them, but I didn't have time to do that, I had 100 cocoa cups to make. They're great quality, and I believe they're waterproof (at least they felt like it). If have to rub the bubbles out once you place the sticker if it's not placed a certain way. I wanted something simple, this was a little more involved...but still not bad. I'm just not the most patient person.”
