Great for applications where you use a lot of ink. These markers are valve actuated. You open the valve by pressing the tip in & resupplying the felt tip with ink from the handle reservoir. So, even if the cap is accidentally left off, the marker will not totally dry out. When the marking gets too light, simply press down and allow more ink to flow to the tip. You can think of the M99 marker as a heavy duty, industrial, refillable Sharpie!
One round tip comes standard with the purchase of a marker. For light usage, the cap should be left on to preserve the marking tip. The main ink supply is stored independently from the tip behind the actuating valve.
Round tip: 4-Pack or by the Dozen
Chisel tip: 4-Pack or by the Dozen
Manufactured from aluminum offering a long life solution to your marking needs.
