Open Stock sold in boxes of 4. An artists´ watercolor marker is the modern definition of watercolor painting: a high-quality drawing instrument that supports spontaneous sketching, artistic watercolor painting, hand lettering and more. The highly pigmented water-based marker is dual ended. It features a smooth flexible brush nib for dynamic sketches, large-scale work or adding all-over color, along with a sturdy fiber tip bullet nib, which can create strokes between 1-2mm for outlines, detailed drawings and adding fine lines. The odorless artist's watercolor ink is extremely lightfast. Colors are consistent wet or dry and are easily blendable. Does not bleed through most paper. The marker has a large ink reservoir and roll-away locks on both caps, to prevent it from rolling off of the desk or work surface. Caps fit on both sides of the marker, therefore there is no risk of damaging the tips when closing. Available in 30 vibrant colors. Sold individually or in assorted sets.
