I saw this thread today and I realize it has been a while but, after reading the site about Minx, it seems that they may be a bit more than just peel and stick. I saw a "heat Lamp" used for applying them, and ,I'm sure,for removing them as well. And since there is on-line training, I bet there is a "prep" involved too. So this may be the answer to why you don't lose the pattern or picture. (kinda like shrinky-dinks remember them?) What concerns me is the cost!!! No ordinary client is going to pay this just for basically "long lasting polish". I would be interested to see if they help with strength, or breakage. I know what I can compare them to, do you have those shrink to fit easter egg sleeves in the UK? Probably something along those lines. Like my signature states, I am not too old to learn new tricks but, I am a bit skeptical. I am still waiting for my popits, and am interested in inverted moulds as well. There will be new things in the future that are superior to the "old reliables". You guys seem to have perfected the Popits, and they are new! I will be excited if they are all they seem cracked up to be. I guess this is just one of those wait and see situations. I think a bit too expensive though.
