Uni Mitsubishi Boxy B&R Black & Red

The Uni Mitsubishi Boxy B&R Pens is an Ultra Fine Marker with superior water resistance that is so good, that once the ink is dry it will not smear, even if water is accidentally spilled on the page. The ink in the Mitsubishi Boxy B&R is extremely light resistant and will not fade even with continuous exposure to light. Very effective because in one pen there are 2 colors of ink that is black and red.
