Be a clever traveler. Here is your full grain leather luggage tag. Glorius. It will hold a business card nicely or just a piece of paper with your contact info on it. Tie or buckle it to your leather bag and go!
Measures 4-1/2" L x 2-1/2" H. For the 18" leather tie strap on the cheaper option, tie a chicken-head knot in it. The more expensive Buckle option has a 1/2" x 10" leather belt. Either will hold just fine. It's just a matter of taste.
