TOMOE Standard 27-digit Birch Beads Value Pack - New Includes a case. Please specify if for a man or a woman. This item is a Tomoe abacus from the era when the consumption tax was 5%. As you can see in the last photo, it cost 10,000 yen at the time. It would probably be a 20,000 yen class item now. Limited to 2 pieces. Thank you for looking.
