Vintage Tooled Leather RLK Keychain Embossed

Vintage tooled leather keychain with the initials RLK on the back. I’ll be honest I didn’t know what this was when I picked it up but google informed me that it is a keychain. It has a snap closure and metal hardware. The keychain is in good vintage condition but there is only one key loop left. 4 inches by 3 3/4 inches
