INCLUDED: This set includes 2 black permanent deep reach markers, 2 ink refill bottles, and 2 replacement tips all stored in a sturdy reusable case. Also called long reach / nib / nose marker. PRECISION: The metal shaft is 3 mm wide, has a reach of 30 mm, and a felt tip of 2 mm that will provide the strictest precision. Perfect for use on most dry and wet surfaces. HANDLING: Easy one-handed handling. Attach the clip to your pants or belt, place your thumb on the top of the clip, push with your thumb and pull with your index and middle finger until the marker releases from the cap. INK REFILLING: Each marker is refilled with a few drops of ink from the included refill bottles. Simply remove the cap, unscrew the marker head, push the foam back into the barrel, and add at least 3 drops of ink. TIP REPLACEMENT: If your tip wears down it can be replaced by removing and replacing the old tip with a pair of pliers. If the tip is too worn down to grip with pliers, unscrew the marker head, push the foam into the barrel, and then push the rear of the tip out from behind. After replacing the tip, place the marker tip down in a cup and wait at least 5 minutes for the new tip to absorb ink. It is recommended to add 3 drops of ink to the foam barrel to speed up the felt tip hydration process.
