Two stainless steel chains, each 36cm long. [Chain 1] The purpose and manufacturer are unknown, but a plate on the chain is engraved with an icon starting with "P" and "Utility Model No. 543644". Web searches suggest it closely resembles a "Petio stainless steel chain dog collar." [Chain 2] The purpose and manufacturer of this one are also unknown. One end has a clasp for attaching to a belt or pocket, and the other end has a hook. It could be used as a holder by clipping one end to a belt and hanging keys or a wallet from the hook. Both items were found while organizing small household items. There are no signs of rust or scratches.
