This is a Chrome Hearts key ring. The fancy chain short with this swivel clip is reportedly very rare. It's quite old, but in relatively good condition for its age. The engravings are also still reasonably visible. Weight: 53.5g The invoice is included, although it's unclear if it's from the purchase of this specific item. I purchased this at a Chrome Hearts authorized dealer in the Toei Kaikan building in Kitakyushu, although that store is no longer there. I'm listing this here because the offers from nearby second-hand stores were unsatisfactory. I've included an image of a reference appraisal price.
