Popura is a less known, possibly obscure Japanese pen company that put a lot of effort into labeling their products with the brand name on clips, nibs and barrels. Since this article about this single Popura pen was published in 2017, more information has come available that fills in some of the missing parts of the story about the brand. This Popura ink shut off eyedropper fountain pen dates from about 1930 to 1937 because of the balance design and that it has a 14 karat gold nib without JIS markings. Unlike many pens from early small Japanese manufacturers that used rather generic hardware and trim pieces, this pen has branded metal parts. The gold plated clip is stamped with the brand name POPURA in a distinctive font. The nib is also stamped with the Popura brand along with full details: 14KT. GOLD over POPURA over REGISTERED over 3 over TOKYO over NIPPON. It’s not known if the company made their own nibs or, more likely, bought them with custom stamping.
