It is so nice not to waist a paper plate anymore. I am not a painter, nor will I ever be one. I just like to paint and, try my hardest to make things work. I just use these and rinse hot water over it and, pull off the dried up paint. Works for me. ★★★★★ Got these for my wife along with an easel that she had been wanting. They seem to work well, cleanup easily and do what they should. View all reviews
