The Tajima PLC2-B900 Ultra-Fine Micro Chalk is 32 oz (907g) of ultra-fine snap line chalk for those big jobs where you want to make sure you don't run out. Micro chalk is the indispensable companion to your Tajima chalk line. This powder is ultra-refined, with micro particles that cling to the snap line for a clean, even stroke. Fade-resistant chalk leaves a bold, visible mark that cleans off quickly and easily. For your convenience, chalk arrives in a waterproof bottle, with an easy-pour spout and screwed nozzle. This Tajima refill chalk is available in blue and red. Tajima Micro Chalk is compatible with any product in the Tajima Chalk-Rite line.
