I found this while cleaning out my parents' house and am putting it up for sale. How about it, sumo fans? Please forgive any age-related deterioration, as this item has been stored at home for a long time. Please consider purchasing if you understand. I would appreciate it if you could register the receipt notification promptly after the item arrives. *Even after a price reduction negotiation is successful, I do not switch to a dedicated listing. Please understand that the transaction will be with the person who purchases it first due to the system. Thank you for looking.
