Watch your words transform on paper with Pentonote's Letters From Fukushima NO.4 Tsurezure no Iro fountain pen ink. The Japanese word tsurezure describes a dull, unchanging monotony, and this 20ml bottle was born from exactly that feeling: the maker found their everyday ink a little boring, and this shade appeared almost by accident as a result.
As you write, the ink shifts unexpectedly from blue to green, a small surprise built into an otherwise steady color. The name plays on that idea: some things stay the same, but it's fun when they don't, and this ink captures both.
Letters From Fukushima is Pentonote's original ink series, each shade tied to a local mood or passing thought. Whether laid down with a glass pen or filled into your favorite fountain pen, this brand new bottle of Tsurezure no Iro adds a quiet, shifting color to your daily writing.
