Additive & Line's MTW-004, Horsebutt dyed with a brown core, Scovill hook, and sinew thread (white) custom. It has an engraved stamp on the front card pocket and a stamp on the inside of the middle layer. Please refer to the photos. There is no oval ring. I used it for about a year, but I'm selling it because I've found another wallet. Please refer to the website for the basic specifications of the wallet.
