The uni-ball PIN is an excellent pen for artists. The fineliners contain fade-proof Super Ink so creations will last the test of time. Featuring a fine tip delivering a solid pigment ink line that is clean and precise. The ink is water-resistant too so the drawing pens can be used with watercolour and will not smudge when wet. This five-pen pack features a great range of PIN fine nib pen sizes. The 0.1 nib creates a strong, slender line; the 0.2 and 0.3 nibs make clear, precise marks; the robust 0.5 nib is ideal for definitions; and the 0.8 nib is excellent for heavy outlines and colour blocking. All nibs are suitable for shading, stippling, layering and hatching. Supplied in a blister pack of 5 pens in fully biodegradable packaging.
