Brushmarkers PRO contain 2.4 ml of paint each. They are produced in the Liquid Ink technology, thanks to which they maintain the colour intensity up to the last drop and allow you to inspect the amount of remaining paint. They are twice more efficient than traditional filter markers. In addition, they are equipped with a Japanese super durable and flexible nylon tip. Brushmarkers PRO contain intense non-toxic colour paints which are dye based or pigment based (neon colours).
