Marsh 88 dye type markers make bold, fast drying, waterproof marks on wood, cardboard and other porous or non-porous surfaces. I's the most economical valve action marker and contains more ink than most disposable markers. They also come with a long lasting fiber tip. Depress the tip and it is ready to use. The valve action uses every drop of ink with no dry-out even if the cap is left off.
