Pigma Micron Fineliner Pens feature archival-quality ink for acid-free environments. These pens are chemically stable, waterproof, and fade-resistant, preventing smears, feathers, or bleed-through on most papers. Certified non-toxic and approved by Acmi, they bear the trusted Ap Seal. Ideal for graphic art, scrapbooking, archival recording, pen and ink illustrations, freehand art, rubber stamps, and cartooning. Due to the delicate nibs, apply gentle pressure to avoid bending. Invented by Sakura over 30 years ago, Pigma ink remains the most reliable permanent ink. Artists, the government, and scientists consider Pigma Micron essential for archival-quality projects. Manga artists, illustrators, and watercolorists use its seven-point sizes for precision lines. At Sakura, we believe in the unique human ability to create.
