Tombow Dual Brush Pens have two tips - a flexible brush tip and a fine-point, hard nylon tip. Both tips are fed from the same ink reservoir ensuring exact color match. Tombow's odorless waterbased inks blend to create any color desired. The colours are water-based and can be used as water-colours and can also be blent. For this purpose, apply the colours to a glossy surface, e.g. an old CD; and blend them with the help of a paint-brush and water. That way you can create beautiful effects and shades! The ABT Dual Brush Pen is a marker with two tips. The fine tip is perfect for consistent lines and tight drawings, e.g. when working with stencils. The second one is highly flexible like a brush – durable, tough and yet soft – and perfect for e.g. large-area colour application. The single ink reservoir not only insures exact colour match but also makes the ABT Dual Brush Pen an economical purchase. The ABT Dual Brush Pen is available in 96 vivid colours. The colours are water-based and can be used as water-colours and can also be blent. For this purpose, apply the colours to a glossy surface, e.g. an old CD; and blend them with the help of a paint-brush and water. That way you can create beautiful effects and shades!
