Custom olive green fountain pen ink made for the Nagasawa Pen Store in Japan.

This new INK is inspired by onomatopoeia.

The Japanese language has a large inventory of ideophones, more commonly know as onomatopoeia, or sound symbolic words. Onomatopoeia can be used to convey the sounds we hear in a day-to-day setting or applied to add a poetic effect to our life. We use onomatopoeia to express ourselves just like we use the language of color to describe our emotions.

Kasakasa (かさかさ)  is the Japanese onomatopoeia for a dry rustling or crinkling sound.
