Tsubame Note has been making notebooks in Tokyo since 1947, founded by Watanabe Hatsusaburō, using an acid-free, neutral paper that can only be produced during spring and autumn — a production window tied to humidity and temperature that keeps the paper's quality consistent. That same acid-free paper is prized for its longevity, with archival tests showing it can be preserved for over 10,000 years without breaking down.This ruled notebook brings that paper into a classic college-ruled format, sewn to lie flat and finished with the same smooth, fountain-pen-friendly surface Tsubame is known for. Available in A5 or B5. Made in Japan. Show more
