Wholly new kind of chalk made of calcium carbonate, our new range of chalk offers excellent writing ,being particulary smooth and legible.
With calcium carbonate being used as raw material, dust does not fly around and few particles of calcium carbonate fall down in the lower tray of the board.
Special formulation prevents dust from sticking to fingers.
Calcium carbonate chalk is better value for money than plaster chalk: it writes much longer and is therefore more economic.
Non-toxic, Calcium carbonate is also used in food,pharmaceutical and cosmetic industries as no case of allergy was reported.
Conforms to EN 71 1-3 & ASTM D4236
