our sturdy chalk sticks and four durable chalk holders come in this multicolor first chalk set. Adjustable plastic holders have a ridged ball end that's easy for beginners to grip as well as a textured band to encourage emerging tripod grasp, so it's great for all ages and abilities. The handy holders also help keep chalk dust off of hands no matter how you grip it! When chalk wears down, it's easy to adjust the holder, making it possible to get every last artwork out of the green, red, blue, and yellow chalk sticks. Refillable and reusable.
