This pen offers the same quality Pigma Ink performance as the regular Pigma Micron pens with a plastic nib suitable for everyday, multi-purpose writing. The durable plastic nib (PN) provides skip-free writing, and a fine or medium line width (.4mm to .5mm) can be achieved depending on applied pressure. Pigma ink is waterproof, chemical and fade resistant, bleed free, quick drying and pH neutral.
