Tombow 6 Dual Brush Bright Coloured Markers Double-tipped markers. Once tip is made of nylon fibre, which allows for a great control over the strokes by being versatile and flexible, just by adjusting the pressure applied on the brush. The other end of the marker has a fine tip, perfect for straight lines or writing. The ink is odourless and water-based, which makes them miscible with each other or other water-based markers, or even watercolours.   Their ink is acids-free and non-toxic.
