Proudly made from nature itself!’ Natural quality: Our exclusive, high quality, Art Makes Sense Blackboard Pastel Chalk is made using purely natural color pigments only. The carefully selected natural pigments give our Blackboard Pastel Chalk rich and expressive colors. No additional synthetic color pigments are added to the Art Makes Sense Blackboard Pastel Chalk to give it their unique color. Our colors are proudly made from nature itself! Consistent quality: Art Makes Sense Blackboard Pastel Chalk was crafted especially for creative drawing as well as writing. While developing our Blackboard Pastel Chalk, we paid close attention to the properties we believe high-quality blackboard pastel chalk should have. The result is a well-balanced and consistent texture, break resistance, color release and adhesion throughout the whole Blackboard Pastel Chalk range.  Strong enough for writing without scratching, perfectly soft for drawing without being brittle! Expressive quality: At Mercurius, the art form of chalkboard drawing is close to our hearts. We feel that drawing and creating in front of children is an essential part of education, and hope that the classic blackboard in schools will remain. We believe that the expressive quality of our Blackboard Pastel Chalk will inspire teachers to continue taking pleasure in their expressive artwork and development ! 12 colours :  Carmine red, Vermillion, Orange, Golden yellow, Lemon yellow, light green, dark green, light blue, ultramarine, pink, White
