Sakura Pigma Micron PN pen. We sell them individually as we love them! They have a a plastic nib, they use archival pigment ink and they are great for everyday writing. (We also sell mixed colour packs of eight and three.)
The durable plastic nib (PN) offers a smooth writing experience.
Archival quality ink is acid-free, chemically stable, waterproof, and fade resistant. No smears, feathers, or bleed-through on most papers and certainly not on an Ink Pot journal!
