Introducing the Kobashi Studio handmade oval key chain, featuring a unique oval chain woven using a vintage chain-making machine. This key chain is meticulously crafted from 5mm Japanese straight brass rod with a matte finish, and its solid brass matte finish and color are expertly controlled by an independent barrel polishing craftsman family in Saitama, Japan. Over time, it will develop a captivating patina through oxidation.

Crafted by a second-generation metal craftsman family, the original solid brass key hook boasts a curved design that fits seamlessly with your belongings, making it ideal for belt loops, coin pockets, or belts. The vintage-style solid brass chain is expertly woven by a master machine operator using a chain-making machine with a century-old history. The wire-rolled rings are sourced from a specialized wire-rolled ring company founded in 1972 in Tokyo, while the solid brass double ring is produced by a respected metal hardware supplier with over 80 years of experience in Tokyo. Handmade in Japan, this key chain combines tradition with exquisite craftsmanship.

Kobashi Studio is a small Japanese Tokyo-based atelier specializing in solid brass accessories of the highest quality and detailing found today. Its founder Junichi Kobashi draws upon completely handcrafted production using vintage machinery and manual processes to create the most special and beautiful brass pieces we have ever seen.
