Uni Pin Drawing Pen Sets contain a range of fineliners for artists and designers in a selection of sizes. These pens are particularly useful for artists who wish to add watercolour washes to their sketches and technical drawings, as the ink is waterproof once dry. Because these pens use a lightfast black ink, artworks created with them will not deteriorate under normal display conditions.
Uni Pin Drawing Pens are available in nine different nib sizes: 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, and 0.8mm.
