Tombow ABT Dual Brush Pens are double ended watercolour felt pens. They are ideal for designers, illustrators, cartoonists and graphic artists for calligraphy, greetings cards, sketching etc. These Tombow ABT Dual Brush Pens feature a fine bullet tip (0.8mm) and a brush tip (0.8 - 3.3mm). The 2 tips share the central reservoir thus avoiding the issue of the most often used tip running out of ink before the other one! The ink is water-based, non toxic, fade resistant and odourless. The colours are intermixable and the addition of water produces magnificent colour gradations. The fine tip is ideal for precise lines and is suitable for scribbling, ruler work or for writing. The larger tip is broad and flexible like a brush, by changing the pressure you can draw fine, medium or broad lines. The high-quality, elastic nylon tips retain their shape. Price per pen.
