Chain wallets come in many different styles, and the most common are the tri-fold as well as the accordion styles. Tri-fold chain wallets can be stashed away in smaller areas than the accordion style wallets because they are smaller over all. You'll also find that chain wallets tend to be a little more heavy duty because the material has to be able to support the chain that is attached to it. This means that the wallet will generally last longer, and you'll be able to get more for your money versus buying a regular wallet.
