Setup, Compatibility & Care
No assembly is required for the Pentel NF450-A. To maintain the life of the marker, ensure the cap is snapped firmly onto the barrel until you hear a 'click' after every use. This prevents the solvent-based ink from evaporating. When storing the markers, keep them in a cool, dry place away from direct sunlight. Storing them horizontally is recommended to keep the ink distributed evenly toward the tip. If the marker is left uncapped for more than 24 hours, the ink flow may become faint; in this case, cap the marker and allow it to rest tip-down for several hours to revive the flow.
