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 box of six fine-tip pens in red, blue, orange, green, brown and black. The ink is water-soluble and wipes off film with a damp cloth, so the same pen can mark a surface you intend to clear again. It suits overhead projection, the black is lightfast, and the housing is 97% recycled plastic. Airplane-safe, and refillable.

• Universal pen for use on almost all surfaces
• Suitable for overhead projection
• PP barrel and cap guarantee long service life
• Airplane-safe — automatic pressure equalisation stops the pen leaking in flight
• High colour brilliancy; black is lightfast
• Housing made of 97% recycled plastic
• Refillable
