Great for a bit of creative play, and to be honest searching for these sorts of things in town is a real hassle, so top marks for Amazon as one click and they arrive. I used with Crayola first paints (non staining) and all worked well, and washed up nicely. I can't comment for other paints. The only down side is some shapes in the packet I received were mis-shappen. But not really a problem. I would recommend for pre-schooler fun.
