This is a vintage wooden hourglass that I found while cleaning out the storage room at my parents' house. It was used in the Showa era. The pillar has a beautiful turned leg decoration. Also, it features black sand. It's a 3-minute timer, but I tested it before listing, and the error was within 3 seconds (within 1.7%) each time over 5 measurements. Size: Height 10.3cm, Width 5.7cm Please consider purchasing, understanding that this item has been stored at home for a long time.
