This meticulously crafted handmade key hook, features a flat 5mm keyring made from premium Japanese straight brass rod with a matte finish. The solid brass matte finish and color are expertly controlled by an independent barrel polishing craftsman family in Saitama, Japan, resulting in a stunning aging process through oxidation after use.

This original solid brass key hook, crafted from the same straight brass rod, is a masterpiece by a second-generation metal craftsman family. Its curved design complements the body, making it a versatile accessory for belt loops, coin pockets, or belts. The solid brass double ring is meticulously produced by a venerable metal hardware supplier with over 80 years of heritage in Tokyo.
