Tombow's ABT Dual Brush Pens work just like watercolour paints and blend effortlessly. They are fantastic to use for rubber-stamping, card-making and of course as watercolours. The fine tip is perfect for consistent lines and tight drawings. The second tip is highly flexible like a brush - durable, tough and yet soft. The brush tip can be dipped in water to create subtle colour washes. Tombow's ABT Dual Brush Pens are loved by comic designers and graphic designers amongst others
