Traditional Showa-retro "wooden abacus," 21 digits. It's a product from about 50 years ago. It has been used considerably, but I think it's in relatively clean condition with no noticeable scratches or stains. Please understand that it is an old item before purchasing. The specific name is written on the dedicated storage case, so it will be shipped without the case. - Type: Abacus, 21 digits - Material: Wood - Color: Brown - Design: Traditional design - Size: Length ≒ 305mm, Width ≒ 65mm, Thickness ≒ 20mm Thank you for viewing.
