New, unopened, and unused. I aim to ship the same day. HAGiHARA Made in Japan Stairway and landing mat with non-slip backing, set of 17 90x21cm 15 pieces, 90x90cm 2 pieces Soundproof, deodorizing, low formaldehyde How about preventing slipping on stairs, reducing coldness in winter, and preventing scratches? I bought it because I have a dog, but since the dog can't climb the stairs, it's unopened, still in the original packaging. I will ship it in the condition shown in image 8, as it was when purchased. Since it is unopened, the images are from the purchase page. ※Quoted from the manufacturer's sales page※ ■Features ◉Thin stair mats that are non-slip due to their adhesive properties. ◉Easy to cut with scissors or a cutter, so you can customize them to fit the width and length of your stairs. ◉Wide enough to cover the width of the stairs. ◉The seams are tile-like, so dust doesn't easily accumulate, and the short pile makes it easy to clean. ◉Washable in the washing machine when dirty. ◉Wide range of uses, such as preventing scratches on stairs, reducing the burden on pets' feet, soundproofing, and preventing coldness. ◉Includes 2 pieces for landings, and also supports curved, special triangular, and trapezoidal winding stairs. ◉Suitable for folded-up and L-shaped stairs. ■Size: Approximately 90×21cm (15 pieces) Approximately 90×90cm (2 pieces) ■Color: Brown ■Surface: 100% polyester ■Back: Acrylic resin ■Remarks: Free cut ■Compatible with hot carpets and floor heating ■Machine washable (drum type not allowed) ■Made in Japan ※Due to the manufacturing process, there may be a size error of a few centimeters. ※Cannot be used folded over the stairs. ※If used in a low-temperature environment, the adhesive function may decrease, and the adhesive surface may lift. ※If you leave heavy objects on the mat for a long time, the adhesive may remain on the floor.
