Price can be reduced if you pick it up. Located in the Hokusetsu region of Osaka Prefecture. Size: Approximately 60 x 60 cm including the edges. Body only: 57 x 57 cm (see photo 5) Condition: Stains and scratches present, one piece has a cut on the edge (back in photo 1). I'm selling these because my child has grown up. Purchased a few years ago at Homes. It was the thickest one in the store. Used for soundproofing and safety. There may not be the full number of edge pieces (19). White and gray sides can be used. I was using the dirty side facing down. Please check the condition carefully before making a purchase, as this is a used item. I used to put a carpet on top of them in the winter.
