This unique spin on the popular Sign Pen includes a brush tip to keep the water-based ink flowing smoothly. The richly saturated colors are fully blendable with water and other Sign Pen Brush colors. The tip can be diluted with water to get a full range of values. Great for a variety of techniques, including feathering, cross hatching, outlining, calligraphy and detailed line work. Wear resistant, pressure sensitive brush tip will not dry out if left uncapped and can be cleaned with a paper towel.
