The best qualities of your favorite Pigma Micron pen, now in a line width for everyday writing! The Sakura Pigma Micron PN Pen has a durable, flexible plastic nib that makes medium-width 0.45 mm marks, while providing the same archival-quality, pH-neutral ink as traditional Pigma Micron pens. The quick-drying, fade-resistent ink is also bleedproof and waterproof, while the nib structure allows for smooth, skip-free ink flow whether writing fast or slow, right- or left-handed, or at any angle. Unlike dye-based ink found in most pens and markers, Pigma ink will not feather or bleed, even through the thinnest paper. Pigma ink is derived from a single pigment to ensure color consistency, and it won't fade when exposed to sunlight or UV light.
