The beloved Tomoe River paper

We use Tomoe River Pocketbook Paper, which is smooth and comfortable to write on, has less ink bleeding and bleeding through, and is highly compatible with fountain pens. This paper is thin and lightweight and in addition to the standard black and blue-black inks, colored inks also look beautiful on it.

Conceived in California, born in Japan

Nanami Paper, a stationery store in California once reached out to us, “We would like to sell notebooks with Tomoe River Paper, but we can’t manufacture the thin paper locally, can we work with Watanabe Bookbinding to make a special notebook series?" The Seven Seas series of notebooks was created in response to this request and Seven Seas CROSSFIELD is the Japanese remodeled version of that series.

Slightly larger 7mm square grid.

The slightly larger 7mm square grid makes it easy to write difficult kanji and is also suitable for bold fountain pens. The blue-gray ruled lines are composed of dashed lines so that they do not repel ink. Printed in a color that is not too dark, it’s designed to not bother the user when writing.
