I purchased 2 boxes of the Crayola Model Magic Class Packs for my grandson's class. They are planning on making a few projects this year. I was very surprised at how much you get in a box and I am sure that they will really enjoy having the color choices. His teacher was thrilled and stated that no other clay works as nicely for the children and that the Model Magic dries quickly. She said that they add food coloring or paint to the white to create some interesting colors. The box came with a little suggestion booklet on small projects. I think the Class Packs are great for classrooms, day camps, large parties etc.
