Classic key ring with a stud that allows opening it for attachment. The key rings are all different because they are made with the leftover pieces of leather. Although we try to make them all more or less the same size there might be some small measurement differences. Monogramming available for this piece for free. Initials or small word (6-7 letters). Add a note when ordering. LAMA brand cold-pressed in the back of the keyring. Handmade using Italian vegetable tanned leather and solid brass.
