Listings commonly call the closure a “Lobster Claw Clasp,” “lobster claw clasp,” or the shorter form “lobster clasp.”
Care varies: some listings specify “Spot” or “Wipe Clean,” while others do not provide any care instructions.
Many descriptions say the lobster clasp and keychain are easy to open and close, making it simple and convenient to attach keys, ID cards, or small items.
Listings often mention companion hardware such as split keyrings or metal rings (sometimes with diameter noted), swivel lobster clasps, and small metal buckles.
Descriptions recommend using lobster-clasped lanyards and charms to hold keys, attach ID passes, secure phones, wallets, small tools or flashlights, and to clip items to bags or clothing for easy access.
