The uni-ball uni POSCA Marker has water-based ink that makes it ideal for creating designs on a variety of surfaces.
Designed with a medium tip, this marker produces neat legible stokes and can be used for a variety of writing and sketching tasks. The marker ink is water-based and does not smudge when used on smooth surfaces such as glass and plastic. You can use it on porous surfaces such as paper and fabric too. It produces a vibrant, opaque colour that can be wiped easily with a wet cloth.
