b7 Bulky (b7バルキー) is a low-density, bulky paper machined at the Japan Paper Ishinomaki Factory. The Ishinomaki Plant was hit directly by the tsunami in the Great East Japan Earthquake. The b7 bulky was produced from the Ishinomaki factory one year after the earthquake as a proof of recovery from the shutdown. "B7" is derived from the developer's favorite guitar chord "B7" and has the meaning of "harmony".
