Double-ended markers. One end, a nylon-fibre brush tip, allows for control over your strokes whilst remaining versatile and flexible simply by adjusting the pressure on the brush. At the other end of the pen, the fine tip is perfect for smooth, straight lines or writing. The ink is odourless and water-based, allowing colours to be mixed with each other as well as with other water-based pens or even watercolours.
The inks are acid-free and non-toxic.
