Karin Brushmarker PRO markers each contain 2.4 mL of water-based paint. Thanks to the "liquid ink" technology featured in Karin markers, the ink remains consistent in quality and vibrancy until the last drop. They are twice as efficient as traditional filter markers and contain nontoxic paints with intense dye-based color. In addition, they are equipped with a Japanese super durable and flexible nylon tip. The colors can be mixed and lightened, plus tonal transitions can be achieved by contacting the ends of two different marker tips. Set colors include neon orange, neon light green, neon pink, neon yellow, neon blue, neon violet, neon yellow-green, neon orange-red, neon canary, neon green, neon red lilac and neon violet blue.Details: Includes assorted colors Brush tips6 packs (12 markers per pack, 72 total markers)Water-based Each marker contains 2.4 mL of paint Durable and flexible nylon tip Nontoxic Intense dye-based colorCan be mixed and lightened Store vertically
