A keyring that uses an industrial part called a snap ring (C-type retaining ring) and has excellent portability. By providing a gap at the tip of the C-type, it can be easily attached to the handle and belt loop of the bag, and on the contrary, the protruding brass parts serve as a spill-proof and are difficult to fall off. When attaching the key, you can easily replace the brass part by simply turning the coin, removing it, inserting it, and tightening it again. Special shapes such as small hole diameter keys can also be used if you use the attached ring.
* Be sure to tighten it with coins. It may come off when tightened by hand.
* This product is intended for both simple attachment and detachment. Please note that it may fall depending on the usage.
