This is a KATO 202, a 0.5mm mechanical pencil made with genuine Karin Kome (Amboyna Burl). It can be changed to a ballpoint pen, KATO 201 gold hardware (+1000 yen). Karin Kome is a burl material harvested only from a part of the root of the Karin tree, and has been popular as a material for high-class crafts since ancient times. It is very beautiful and precious. Among them, genuine Karin Kome often has complex grain patterns, and above all, it has a sweet scent! This one has a very fine grain and is highly recommended♪ Unfortunately, the grain doesn't show up well in the photos...
