The best material for your keychain will depend on how you plan to use it. If you’re attaching it to your car keys for everyday use, look for a durable design made from leather or brass. If you’re using your keychain to accessorize a backpack or for special keys that are used every so often, look for an acrylic design. Etsy sellers can customize these keychains to feature a name or word, like “mailbox” or “back gate,” to keep you organized. If you’ll be using your keychain outdoors while hiking or camping, consider a brass keychain with a carabiner style attachment. This design is both hardy and easy to attach securely to a zipper or bag for safekeeping.
