The strong colour pigments in Mercurius blackboard chalk allow for luscious applications. The colours have a high coverage and are still easily blended on the board. The square-shaped chalk has a removable paper wrapper to stop colour from getting onto the fingers.
The colours follow the Stockmar colour range.
