越前國 甚六作 Jinroku Saku

"Jinroku" is a tribute to the name of Masayuki Hasegawa's father, who was a eyewear craftsman in Sabae City. Jinroku is renowned for mastering the handcraft of using celluloid, metal and acetate all at the same time.

After graduating from high school, Masayuki Hasegawa became an eyewear craftsman and has since produced countless frames. He established the brand "Echizen Jinroku Saké" and, in collaboration with designer Seishi Mitani, combined "innovative design" and "traditional techniques" to create a diverse range of frames in different styles and types, making the products of Echizen Jinroku Saké popular among handmade eyewear enthusiasts.

One of its highlights is the use of cellulose acetate to make glasses. After being hand-polished, cellulose acetate exhibits a charming color and gloss similar to that of a tortoise shell. This material requires a long drying time, and only a few brands still choose to use it today.
