These high quality chalks made with food grade pigments are used in Steiner schools all over Australia to create the beautiful chalk drawings in class. Completely free of any heavy metals and toxic ingredients and they come with twelve beautiful colours!
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.
