Price not negotiable. Although it's a new item, there may be some minor scratches from storage. These are lovely indoor slippers, perfect for guests, parent-teacher conferences, entrance ceremonies, graduation ceremonies, and other occasions. The size is 37, which I believe is 24cm. However, when I actually tried them on, they fit me perfectly, and I usually wear a 23.5-24cm wide size. So, if you prefer a little extra room, they would fit a 23cm to 23.5cm foot.
