The Uni-ball PIN is an excellent value drawing and sketching pen with fade proof and water-resistant ink in a range of sizes.

Being water-resistant they are ideal when used with watercolour as once dry the ink will not smudge when wetted, or they can be used on their own for drawing and inking in pencil sketches.

The nib is supported and protected by a steel collar meaning the PIN drawing pens are long-lasting and will not be damaged from use with stencils.
