The Crayola 48-piece pavement chalk set is designed for outdoor artistic activities on concrete and pavement surfaces. These chalk sticks feature an anti-roll shape to keep them in place during use and are formulated to be washable, allowing for easy removal from most surfaces. With broad nibs, they are suited for children aged 3 and older to explore bright, matte colours while creating large-scale drawings. This set provides a versatile tool for creative play, whether for individual art projects or group sessions. Adult supervision is recommended due to the potential choking hazard of the individual chalk sticks.
