The Sakura Pigma Micron PN 8-Piece Colour Pen Set features a durable plastic nib (PN) engineered to provide ultra-smooth, skip-free lines for everyday writing and drawing. Filled with iconic, archival-quality Pigma pigment ink, this pack contains eight vibrant shades that dry rapidly to a completely waterproof and fade-resistant finish. The robust polyacetal structure allows left and right-handed users to easily adjust their line widths between 0.4mm and 0.5mm based entirely on personal writing pressure.
