Crayola Twistables Coloured Pencils put a new spin on creativity! Just turn the ends to twist up vibrant colours. Whether they're layering or blending colours, filling in drawings or outlining letters, kids will have all the colours they need to create vibrant illustrations. Twistables combine the best of pencil colouring and mechanical sharpening--no external sharpener or peeling needed when your pencil gets worn down. The clear plastic case lets you see how much colour is left and protects the coloured pencil lead from breaking when kids are colouring hard.
