The Brushmarker PRO Blender is a brush type marker specially designed for illustration, calligraphy and lettering. The Blender is transparent, colorless; use it to blend colors into each other, to make single-tone gradients, or to blend and create new colors. Traditional brush pens and markers come with a piece of felt or cotton soaked in ink, but the Karin Brushmarker PRO come filled with liquid ink: the tip will always be juicy, you can draw or color with a constant flow of ink, without dry effects, and you will take advantage of every last drop of ink. The tip of the Brushmarker PRO is a medium-sized flexible brush, ideal for obtaining from fine to thick lines. This tip is resistant, so you can use your Brushmarker on both smooth and textured papers, such as watercolor.
