Sakura Pigma Micron Pens, Black & Gray, 10/Pack (SAK50146)

The fine nib makes this pen ideal for creating both technical and artistic drawings. The fineliners have a protective metal sleeve around the extended tip to give extra control and increased resilience when used with drawing aids such as rulers. This permanent, fade resistant, chemically stable, pigment-based ink will not bleed or run if liquids are spilled on or applied to the document after the ink has dried. Perfect for legal situations, Pigma ink is nearly impossible to alter on documents, in log books, or on checks. Architects, archivists, anthropologists, entomologists and laboratories depend on Pigma Micron for record keeping. Pigma Micron is the first disposable technical pen using archival pigmented ink.
