Rainbow Pencils function like regular wooden pencils, and are the same size and weight, but they’re not made from wood, they’re made from lots of layers of recycled waste paper. So the shavings / sharpenings look like rainbows.

Making Rainbows
You don’t need a special sharpener to make rainbows, but a sharp, good quality one will help you make better ones. To improve your rainbows, you can try sharpening from the other end of the pencil, using a better sharpener or applying a more constant force when turning the pencil. Trying to make the perfect rainbow is all part of the fun!
