This is a keychain with a brass carabiner and a chain attached.

The great thing about this key lock is that you can use it without removing it, even when it's attached to the inside of your bag, the handle, or your belt loop.

The large double ring makes it easy to organize your keys.

The chain is attached to an original carabiner made by hand using round brass wire.

The leather part is made of nubuck, a matte material created by lightly sanding the cowhide leather, and the more you use it, the more glossy it becomes.
