Keychains are both fun and functional. Photo keychains are a great way to share memories and work well as grandparent gifts, for instance, and leather keychains are a classic option for accessorizing your look. Often used as party favors and souvenirs, keychains are a practical gift idea because of their many potential uses. Etsy sellers create keychain wallets that make it easy to carry identification and other important things without the need to carry a full bag. Carabiner keychains clip easily to other keychains and have a variety of uses around the house, too. Etsy sellers create keychains in all these styles and many more, and you can choose from a variety of customization options including text, color, design, and size.
