Keep your leather wallet secure with the chain add-on. I personally use a chain on my wallet whenever I hop on a bike, travel, or am in any area with a lot of people in close proximity. I use a special type of solid brass hardware to attach the chain directly to the rivet for maximum durability. Typically installed into the lower right corner of the wallet with a small split ring attached. This means you can swap out your chain at any time, or go without it if you don’t need it for a week or so.
