Waterproof and mold-resistant adhesive-type cushion floor! I bought it for my rental apartment, but I won't be needing it anymore as I'm moving. It's unopened, still in the cardboard box. I opened the cardboard box once to remove the receipt inside. The product itself is brand new. I purchased it from Rakuten Ichiba for ¥5,990. - Size: Approximately 183 x 91.5 (cm) (for one tatami mat) - Type: Adhesive type - Waterproof: Waterproof and mold-resistant - Suitable for rentals: OK for rentals - Compatible with floor heating: OK for floor heating - Color: Concrete-style gray Thank you for looking.
