MAXI-COSI Back Seat Protector This is a protector sheet/protective mat with non-slip properties to protect your car's seats from scratches and dirt. (No. QNY3203201500) I used this for about six months, but I am selling it because I no longer need it. There is no noticeable dirt, and I think it's relatively clean. However, please be aware that there are some scuffs and folds from use. There is no box, only the items shown in the photos.
