This Tombow ABT Dual Brush Pens Grey Colours comes in a set of 12 assorted shades of grey. Tombow Dual Brush Pens are particularly popular with comic book designers, graphic artists and watercolourists. Each Tombow Dual Brush Pen has two tips: a fine one that’s perfect for details (line width 0.8 mm) and a flexible brush (line width 0.8 mm - 3.3 mm). The brush tip is durable yet soft, and you can easily use it to create fine, medium or broad strokes. It’s also ideal when you want to fill larger areas with colour. The ink inside the pens won’t bleed, and is odourless and acid-free. Colours are not light resistant. Since it’s water-based, you can blend the colours, just as you would with watercolour paint. Ideal for all arts and crafts, illustration, typography, manga drawings, card-making, rubber stamping, scrapbooking and more.
