Do not be fooled - Regular consumer-type markers sold in stationery stores will not hold up in industrial applications.

For making a strong impression, wet, long-lasting marker ink withstands the rigors of even the most demanding industrial applications and environments. Built specifically for industrial use, the outstanding quality of every Marsh Shipping Supply Co. product far surpasses any other marker available.

Valve markers have been in use for over 50 years. When the tip is pressed down, it pushes onto a spring-loaded plunger which opens the valve, letting the liquid through to the tip and allowing the user to regulate the quantity of liquid dispensed. When the cap is left off, the tip can be re-primed, so you can use all the liquid inside the marker.

Marsh® markers last longer than other disposable markers because they contain more ink. And no ink is wasted in our valve-operated markers as it flows uninterrupted through a hollow chamber. So Marsh® markers stay wet for thousands of uses.
