Hang this little guy on your belt loop, bag handle, or wrapped around your fingers while running errands, and attach your keys to it for added benefit. The cardholder itself is very spacious, and can hold cards, cash, business cards and coins (throw the coins in the back behind everything else to keep them secure). It also makes an excellent gift: these tend to be bought in pairs or triples to be kept for gifting throughout the year to friends, family and coworkers. 

The keychain (updated in 2023 to be a thicker leather with a different snap) component has a snap, not a rivet, allowing the small strap to be opened and attached to anything you want!
