☆ I purchased this from 3COINS before, but it didn't fit my stairs, so I've kept it unopened at home. ☆ This is a set of 15 mats, with 5 mats in each bag (3 bags total). Please note that the bottom of the sticker on one bag is slightly lifted (see photo 4). ☆ These stair mats can be placed on each step, and the back has non-slip material to prevent slipping. They help reduce footstep noise, prevent scratches, and can also keep your feet warm in the cold season. They are recommended for homes with small children or pets. They can be hand-washed if they get dirty, so you can keep them clean♪ ☆ Although it is new and unopened, it has been stored at home by a private seller, so please refrain from purchasing if you are looking for a perfect item or are very particular about condition. m(_ _)m
