Thank you for viewing. This is an old five-bead abacus that was at my parents' house. It is believed to have been used from the early to mid-Showa era, but the details are unknown. It has been stored for a long time, so there are stains, blemishes, and slight chips on the beads, but it functions normally. Please consider the above before purchasing. - Type: Abacus - Material: Wood - Size: 32cm (height) x 11cm (width) x 4cm (thickness) Thank you for viewing.
