Lumocolour permanent marker features Dry-Safe ink so it can be left uncapped for days without drying up. When left open during breaks in writing, it remains ready for action without delay. Lightfast, colour-intensive ink is waterproof and smudgeproof on almost all surfaces. Neutral-smelling, xylene-free ink dries in seconds so permanent marker is ideal for left-handers. Chisel tip remains locked in place and cannot be pushed back into the barrel even with extremely heavy writing pressure.
