Diving Boots GULL 23cm Purchased used and used for diving, rock pooling, and river play. There are name markings, so I marked it as "has some scratches and dirt," but otherwise, there are no noticeable stains. Can be used not only for diving and snorkeling but also as water shoes. The zipper moves smoothly, making it easy to put on and take off. Please understand that this is a used item.
