Fuka Pita PLUS Underlay Rug This is an underlay to be placed under a rug. It prevents cold from the floor and prevents the carpet on top from slipping. It has creases from being folded and stored for about a year and a half. I am also selling a low-rebound rug separately. We also offer a discount for combined purchases! * When used together, the fluffiness increases, but the size difference is only 2cm, so the underlay will be slightly visible ( >_< ) Dimensions: 148 x 148 cm Material: 100% polyester Thickness: High-rebound urethane 20mm Color: Gray Functions: Soundproofing, non-slip, compatible with floor heating and hot carpets Please understand that this is a used item and that it has been inspected by an amateur before purchasing. Thank you for looking.
