Tombow Dual Brush Pen Sets contain 10 carefully chosen colours, which form a specific colour palette. Tombow Dual Brush Pens are perfect for hand lettering, journaling, doodling, drawing and sketching, colouring in, cardmaking, crafting and more! They feature two nibs allowing you to create a variety of strokes and effects. Using the flexible nylon fibre brush tip, you can achieve fine, medium, or bold brush strokes simply by changing the pressure on the point. The resilient tip springs back to hold its shape, stroke after stroke. With the hard nylon tip, you can create consistent lines, tight drawings, borders, copy markings, fine lettering and colouring in. Tombow Dual Brush Pens tips can also be dipped in water to create subtle colour washes! The ink is water-based, odourless and can be easily blended. It is also acid free giving you long-lasting artworks.
