The name Iroshizuku is a combination of the Japanese words Iro (Coloring), expressing high standards and variation of colors, and Shizuku (Droplet), that embodies the very image of dripping water. Each ink name derives from the expressions of beautiful Japanese natural landscapes and plants, all of which contribute to the depth of each individual hue. Each glass bottle contains 50ml of ink suitable for use in all fountain pens. If you wish to use this in the fountain pens sold on our site, you may need to purchase an additional converter to do so. Most Pilot pens are sold with converters or do not need one (with the exception of the Retro Pop line). Our Y Studio pens do not need an additional converter for bottled ink. Our Kaweco fountain pen converters are all sold separately,
