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.
