This is a Chrome Hearts phone case. I purchased it over 20 years ago at the Aoyama main store. Since we're in the smartphone era now, I hope someone can find another use for it. It might also be a good collector's item, as they won't be made anymore. ※ Photos 10-12 show examples of use. ※ As the photos show, it will not fit iPhones, Androids, etc.
