iroshizuku Fountain Pen Ink Mini Box Set

A combination of the Japanese words: ‘iro’ 色 meaning colour and ‘shizuku’ 雫, translating to dew or droplet.
PILOT iroshizuku reflects our mission to distill the unique beauty of the Japanese landscape into every colour droplet found in each bottle of fountain pen ink.

No - most fountain pen inks are water-based/water-soluble and the rich, vivid colours available within the PILOT iroshizuku range could not be achieved with a waterproof formula.

The advantages of water-soluble inks are that they are more well-behaved and require less maintenance when used in fountain pens. With the pigments or iron gall particles that are used in waterproof inks, there is a risk of clogging or damaging your fountain pen, especially if left in it for a long period of time.

Another enjoyable aspect of using water-soluble inks, especially when sketching and painting, is the ability ‘pull colour’ from the ink like you would with watercolour paints. Further dimension can be added to a sketch when using a wet paintbrush.
