The nib is fine! Don’t worry. In fact, it’s more than fine: It’s a Concord, by none less than grandmaster Yukio Nagahara (“Nagahara Junior”), who recently started his own business, The Nib Shaper. But let’s start from the beginning.

It was a busy weekend at Bungubox in Omotesando: Nagahara did nib grinding, Eboya had a small pop-up shop around the corner, and Ken Takeda (who recently appeared on The World Unknown To Matsuko to talk about ink) did “ink fortune-telling”.

Eboya is a Tokyo-based pen maker that has been around since 2009. Their specialty is pens made of ebonite, polished on traditional rokuro lathes. Eboya’s parent company is Nikko Ebonite, the only producer of ebonite in Japan.

Eboya has seven pen fountain pen models, including the Onoto-inspired Kyouka, the bamboo-like Ricchiku, and the torpedo-shaped Houga. Each model is available in several types of marbled ebonite, in small, medium, and large sizes, with an appropriately-sized 14K Bock nib in F, FM, M, or B.
