Sailor Kiwa-guro - Waterproof Pigment Ink
This deep black is the créme de la créme of Japanese-made inks. It's formulated by Sailor, a company with over 100 years experience, renowned for their beautiful writing instruments as well as their inks.
This is a waterproof*, light-fast archival deep black ink, perfect for creating anything that you'd like to last a long time (with no fading or reactions with the paper) or if you want to apply more inks or watercolours over linework without the risk of smudging.
It's slightly different from my own pigment ink with a slightly quicker drying time and is an even deeper black.
This beautiful ink is the perfect pairing with a Tom's Studio Lumos, Wren, or Fountain Pen. Each bottle holds 50ml of stunning ink, allowing your creativity to flow across countless pages.
*Waterproof? Well, almost. This ink is highly water-resistant, meaning it’ll stay true under a colour wash – provided you’ve given it time to fully dry. But if you go in heavy with a very wet overwash, you might notice some smudging. Unlike true waterproof inks (which often contain plastic binders), we’ve formulated this one to work beautifully with the Wren and Lumos – balancing flow, performance, and durability.
