These are floor tiles I found at my parents' house. The ones in the back are flooring material that doesn't require adhesive. They seem to be from Tansu no Gen, and there are enough for about 9-10 tatami mats. 5 boxes are dirty, and one tile is broken. A new product costs 52,800 yen for 12 tatami mats on the official website. - Quantity: 12 pieces x 6 boxes - Area: Approximately 9-10 tatami mats - Size: Length 122cm - Product Name: Floor Tile - Model Number: A3002 Vintage White I'm looking for someone to buy them all together, including shipping.
