HAGOROMO Fulltouch Luminous Chalk 1 Box, Non-Toxic, Dustless [72 Pcs/5 Color Mix] WELL COATED AND DUST FREE: The only thing worse than chalk breaking in half is getting dust all over your hands and clothes when writing on the board or drawing on the sidewalk. All Hagoromo chalks are well coated to prevent hands from coming into contact with chalk dust when using. LUMINOUS CHALK: Clear, vivid and bright luminous colors are effective at highlighting important topics in lectures, writing work instructions at construction sites or adding a pop of color to an art piece. Bright colors grab student's attentions quicker and make them more concentrated on the information at hand. Especially ideal for students with weak color sensations/identification as well as short-sighted students as vivid colors can be seen from a distance NO MISTAKES: Our chalks erase easily leaving little to no residue on the chalkboard when removed. Chalk generates little dust and fallout minimizing chances of smudging and messes when writing or drawing ECONOMICAL USE: Unlike other chalkboard or sidewalk chalks, Hagoromo chalk is highly dense meaning that their shelf life is longer as it is consumed very slowly due to compression molding, drying system, and special thermal treatments. There is no need to use a lot of chalk to generate vibrant and colorful art, a little goes a long way! NON-TOXIC AND ECO-FRIENDLY: Made from high quality natural calcium carbonate, this product is non-toxic and safe for kids and professional use. Every single Hagoromo chalk is packaged and inserted in foam slots one by one to avoid breakage.
