Zig Clean Color Dot markers have a 0.5mm fine tip on one end and a unique dot tip on the other end that allows you to easily draw dots by pressing the dot tip onto paper. The harder you press, the bigger the dot! This marker is ideal for dot decorations, creating mandalas, or bullet pointing to-do lists. Each marker is made with water-based pigmented ink that is lightfast, odorless and xylene-free.
