This leather Bear Trap Coin Purse is just plain cool. I keep all of my Pesos in it for when we travel to Mexico. There are two pieces of custom made spring steel in the top part that cause it to want to stay closed. Of course our leather is full grain leather so it will just age well as it gets older. Because it is leather, it will also stretch to hold the amount of coins you need it to. It's just a plain fun leather change holding coin purse to keep the coins in your pocket, briefcase or in your car, organized.
