Box Sushi / Pressed Sushi Wooden Mold Set - Shōwa Retro This is a complete wooden mold set for making box sushi / pressed sushi at home. I used to make box sushi / pressed sushi at home, and this has been stored at home recently. It's a Shōwa retro item. It's a used item with minor scratches and discoloration, but there are no problems with its practical use.
