Keychain is a straightforward accessory that hangs from your belt loop or purse strap. It's designed to keep keys organized and easily accessible. The small metal ring on which the keys are attached can be made of various materials such as brass, aluminum, or stainless steel. Typically, keychains have one or more rings to hold multiple keys in place. Some may also feature additional storage compartments for other items like a house key, car key, or even a USB drive.
