These ingenious, triangular shaped crayons won't roll away. Made of plastic, not wax, for additional durability, this set of 24-rainbow color crayons stay on the table--just where your little artist put them! They pack into their own sturdy, plastic flip-top case for easy clean up. The unique shape will help kids develop the preferred grip for later writing skills. Melissa Doug was started 20 years ago, by a real Melissa and Doug, in the garage of Doug's childhood home, where occupational priorities included not disturbing Doug's parents. The company has grown and moved, but its founders' philosophy remains unchanged: to make each and every customer a happy and permanent member of the Melissa Doug family.
