Unshudo Soroban (Abacus) - Wooden 27 digits, approximately 39cm This item is from the Heisei era. It's an old item, but it's from a time when quality was highly valued. It has been stored at home. The beads are in good condition, but the movement of the beads is a little stiff, so we recommend using a special lubricant. We hope it can be useful for things like trial lessons at a cram school (^^) We will carefully deliver it via Takkyubin (Home Delivery Service) in a 60-size package.
