They don't stick!
These are cute and can be used on many different projects, but they do not stick. They are supposed to be self-adhesive, but I haven't had one letter off of my 3, count them THREE!, packs of these that stick on it's own. No biggie really, because I can just use a little liquid adhesive to stick them myself, but if they are supposed to stick on their own I expect them to do so. Otherwise I could cut my own letters out or pay WAY less for some other letters that aren't supposed to stick and I wouldn't be so aggravated!
