Koh-I-Noor Magic pencils write in multiple colours at once thanks to the clever design of their leads. The lead inside each pencil is made from multiple strips of different colours which run all the way through the pencil. Colour combinations vary from lead to lead and change as you turn the pencil in different directions. These jumbo pencils are triangular in shape and are guaranteed to add some excitement and colour to your drawings! The pack includes twelve colour changing pencils and one blender pencil.
