"I purchased these for my preschool class. Thouht they'd be a great project to send home as a Christmas decoration.
The pieces to be colored have a wax on them so crayons and colored pencils don't work very good - the kids didn't get the results they wanted. We switched to markers and they worked, but are so dark, it's hard to see the outlines printed on the pieces.
It's a lot of work for preschoolers to do all of the pieces - both sides need to be colored. I would recommend these as long as you know about the type of paper used and have the kind of time to complete the project."
