For some amazing pencil history, please see the cyclingpencils blog. Written in Japanese with photo titles and partial text in English, the last two posts tell a story about a pencil that may look familiar at first glance – the H. A. Faber “Fortress”. But H. A. Faber isn’t a distant member of the Faber pencil manufacturing family, and the “Fortress” is not a “Castell”, even if similar fonts and logos are used.
It turns out the brands came from Hirohachi Akagi & Co., founder of the Colleeen pencil company. There is also a “Moon Glove”, with moon and globe logo, very similar to the Staedtler logo.
