Our chalk is the whitest compound available! It will even stand out on crushed limestone. Made from the highest quality calcium carbonate (marble dust). It is completely safe for players, equipment and turf. Conforms to all safe-use requirements of the consumer safety act, NCAA & NFSHA official rules and all known Little League rules for athletic marking materials.
It comes packaged in 50 lb. bags. To figure out how much you need, follow this simple rule of thumb: one 50 lb. bag of chalk will stripe approximately 300' at 2" wide and 1/16" thick line.
