Unique Design: When you open the oval key rings, they click and stay open, then snap closed easily. They also won't open accidentally and are easier to install than opening a key ring. They are very strong and durable. EASY TO USE: The connector breaks off when you pull up to open. It locks in the open position! Easy to remove and install. Then when you are ready to close it, just place it between your thumb and index finger, pinch it from both ends, and it will snap and lock into the closed position. Multifunctional accessories: ① Key ring: It is easier to add or remove keys. ② Small keychain accessory: Can be used as a connection between key ring and keychain. ③ Small chain connector: Use it to clip your phone to your wristband. Can be used with paracord lanyard. ④ Mini key clip: Clip your keys to your work bag. ⑤ Use as a jump ring on a necklace.
