This is a small leather key fob / key-chain made of leather and a solid brass key ring. The leather is cut by hand, lightly oiled, beveled, burnished, waxed, stamped, and hardware affixed.

The color will darken over time as it develops a patina unique to you and its environment. Sunlight and oils from your hand will give it a unique color after a few months and continue to develop for the first couple of years. If you'd like to speed up the aging process, leave the key fob in a sunlit windowsill and alternate the side that faces up.
