LUMOCOLOR GREASE PENCIL-BLUE

Staedtler grease pencils (aka dry markers) work great on smooth surfaces, especially for marking on glass and dark surfaces. They are intense and rich in color and feature a soft lead that is water-soluble. The pencils can be easily removed with water from smooth surfaces like metal sheets, lacquered and galvanized metal, rubber, PVC, leather, textiles, lacquered and coated wood, stone, glass, porcelain, and paper. They also work great on dark and transparent surfaces, even if they are dusty. Grease pencils are not as precise as the alcohol pens, but they are much faster and more versatile
