Magnetoplan chalk markers filled with a highly opaque, low-odor water-based liquid chalk. They write on smooth surfaces such as glass, tiles, mirrors, metal, plastic (bistro) boards, etc. Windows and shop displays in schools, kindergartens, and more can also be easily painted and described with the chalk marker. The markers have a round tip with a line width of 0.5 - 3 mm. Available in assorted colors: black, white, bright yellow, and bright pink. The applied liquid chalk can be wiped off with the Magnetoplan PRO+ board eraser or a dry cloth. For rougher surfaces, we recommend using the liquid Magnetoplan board cleaner or a damp cloth for cleaning.
