We are pleased to unveil our new K-55 Fluorescent Water-based Paint Marker. The new water-based inks are environmentally friendly, odor free, and perfect for use indoors where solvent fumes are undesirable. True to their name these fluorescent colors will glow under a black light, but beware, the color is just as striking outdoors! The K-55 is available in 5 colors. 30ml
