No, the paint sample ones don't pill and stick... they don't come off to easily, they bend pretty easy.
I still give my little ones the paint colors to match. The 2 and 4 year olds don't know to look for the name of the color on the back and the older girls will "play" with the little ones and don't cheat... what would be the point since they are playing to do something with the little ones, not to win.
I was planning on just glueing the whole card onto some paper and cutting them out. But the kids were enjoying them right from the store, so why put that much time into it!
BTW, we went to Disney in May, I gave them the "Mickey Matching Game" just after Christmas (they helped pick out what colors they wanted for the game at the store...) and they will still sit down and play with them!
They like playing with the paint Mickey's more than any of the other matching games we have in our game room... I think there are 4 different ones down there!
Mickey Heads Rock!
