Anti Dust Blackboard Chalk in White, Yellow or Assorted Colors, 12-Pack

ANTI-DUST CHALK FOR BLACKBOARDS  Write on the blackboard without chalk dust or chalk fingers? It’s possible with this hard blackboard chalk that comes in single packs of white, yellow or an assortment of colors. Each pack includes 12 pieces. RESIDUE (GHOSTING)? This chalk works especially well on glass boards and well-primed chalkboards; however, it can leave a residue on certain blackboard surfaces that have not been primed correctly or that have been handmade from some DIY paints. Helpful Hint: Always prime your board with a piece of white chalk before using any color chalk.  CHALK DUST Any chalk can cause dust, but the hardness of this chalk minimizes it to be almost not there while writing or drawing on a blackboard when compared to other, softer Blackboard chalks. (Note that friction from travel may create a small amount of dust in the carton upon arrival.)  DETAILS Zuid-Hollandse krijtindustrie Blackboard Chalk Anti-Dust Cardboard Box 12 pieces White, Yellow or Assorted Colors
