Tajima’s Ink-Rite Quick Dry Snap-Line Ink produces a quick, neat line faster and more precisely than a marker and straight edge. On porous surfaces, the quick-drying ink makes a bold marking line that’s easy to follow, and it produces a fine line even on non-porous surfaces. The bottle holds an incredible 6 oz (180 ml) for many refills to come. The screw-cap nozzle dispenses ink easily and neatly. This quick drying ink makes semi-permanent markings that are scuff-resistant and smudgeproof on work surfaces, yet wash off skin easily with soap and water. Tajima Ink-Rite snap line ink comes in your choice of black, blue, or red.
