Scribble Crayons are made from broken and/or used crayons. They are melted together in a mini-muffin tray, which gives them their rounded shape. They are just the right size for younger children to hold and kids won't get discouraged by accidentally breaking crayons. Each one of my Scribble Crayons has multiple colors melted together. Because each is completely unique not only due to the colors mixed, but the unique melting patterns, each crayon is one-of-a-kind. When you color with them, you can never be certain which color will come next! Unless specifically noted, all Scribble Crayons have at least four colors mixed in.
