Pigma ink, invented by Sakura over 25 years ago, continues to be the most reliable permanent ink on the market today. Artists, consumers, the government, and scientists consider Pigma Micron a necessary basic tool for any archival-quality, handwritten project. 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. It’s no wonder architects, archivists, anthropologists, entomologists and laboratories depend on Pigma Micron for record keeping. Manga artists, professional illustrators and watercolorists use the seven point sizes to create precision lines. Scrapbook enthusiasts and crafters require its archival quality for preserving memories in journals, and for making cards, quilts and dolls. Use Pigma Micron to leave a mark that will last a lifetime. Sold individually.
