We now are offering Giotto Anti-Dust Blackboard Chalk. Made from real calcium carbonate chalk from France, these round chalk sticks are designed for use with chalkboards. They glide smoothly across the board without scratching and leave a clean, sharp line. Erasers easily without any residue. Dermatologist tested and dust-free. Does not contain gluten.
This chalk is for children 3 and older - small pieces could be a choking hazard.
