Lumocolor® non-permanent pen 316 is STAEDTLER's universal marker — one pen that writes on almost any surface rather than a drawer full of surface-specific ones. This is the STAEDTLER box of 4 fine-tip pens in assorted colours. The ink is water-soluble and wipes off film with a damp cloth, so it can mark a surface you intend to clear again. It dries fast, which suits left-handed users. The fine 0.6 mm tip suits overhead projection, the black is lightfast, and the housing is 97% recycled plastic. Airplane-safe, and refillable with the 487 15 station.
