Sailor - Fountain Pen Ink - Nano - Seiboku (Blue)
The Sailor Nano Seiboku is a pigment-based blue fountain pen ink. Unlike dye-based inks, Nano Seiboku uses nano-particle pigments that remain suspended in water for consistent flow. The result is a water-resistant, light-fast blue that holds up to moisture once dry – suitable for documents and archival use. Compatible with all fountain pens.
Specifications: 50ml | Pigment ink | Water-resistant
