Lumocolor® permanent pen 314 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 four broad-tip pens. The ink is permanent, smudge-proof and waterproof on almost all surfaces, and dries in seconds — which also makes it comfortable for left-handed users. DRY SAFE means it survives days uncapped. It suits overhead projection, the black is lightfast, and the housing is 97% recycled plastic. Airplane-safe, and refillable.

• Suitable for overhead projection
• PP barrel and cap guarantee long service life
