Thank you for viewing! ෆ‪·͜·ᰔᩚ This is a new type of chalk that offers a gentle, bright, and fluffy color palette not found in regular chalk.♪ Because it's thick chalk, children can enjoy drawing not only on blackboards but also on concrete (easily washable with water), allowing them to play freely beyond the confines of paper!♪ Material: Calcined gypsum *Please note that there may be slight scratches or chips on the chalk from the beginning. To secure the chalk during shipping, we will insert thick paper without opening the package.⭐︎ Please understand and purchase. Thank you.
