Liquid Chalk Pen
White liquid chalk stays on after even rain and general watering, but it can be removed with a moist paper towel. The makeup of these chalk markers allows them to dry and crust over to maintain water/fade protection. Once the crust of the chalk has been broken, the liquid chalk easily washes away. Older writing can be cleaned with an alcohol based hand sanitizer. Chalk pens are convenient for use with smooth faced T-signs and vinyl card signs and should not be used on ruff textured black board T-signs. Color: White.
