Crayola Twistables Crayons put a new spin on creativity! Just turn the ends to twist up 12 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 crayons and mechanical sharpening - no external sharpener or peeling needed when your crayon gets worn down. The clear plastic case lets you see how much colour is left and protects the crayon from breaking when kids are colouring hard.
