Material: PVC, Polyvinyl Chloride Brand: UXPRIN Product Dimensions (L x W x H): 45.7 x 45.7 x 0.1 cm Color: Marble Type SW009 Shape: Square Item Diameter: 45.7 centimeters I mistakenly purchased the non-adhesive type, so I have opened the box, but the product is new and unused. I will ship the item by attaching the address label directly to the packaging box. 24 pieces, enough for 3 tatami mats Thank you.
