Sailor Inks are fountain pen-safe, available in a wide variety of formulations and colors, and like Sailor pens, offer terrific value. Longtime standards Black, Blue, and Blue-Black are augmented by three water resistant pigment inks, Kiwa-Guro Black, Souboku Blue-Black, and Sei-Boku Blue, while additional nuanced colors are available on a rotating basis.

Sailor bottled inks are suitable for use in any fountain pen with a converter, piston, or eyedropper filling system, while Sailor cartridges are only used in Sailor brand cartridge-converter pens.
