I only wore these once in front of the entrance. I then stored them for about six months. They are generally clean, but please understand that a child used them once before purchasing. Size: L (23cm-25cm) These are not part of a set with skates, but I will also include separately sold knee pads, elbow pads, and wrist guards. ☆Please Read☆ Thank you for looking. Please read the product description and view the photos carefully, and agree to the terms before purchasing. I strive to ship promptly after payment. I am also selling on other flea market sites, so I will give priority to the person who makes the payment first, even if negotiations are ongoing. I am selling items that are clean and still usable, but please understand that there may be oversights even though I check them, that they are stored at home, and that they are not new or unused. I do not have any pets, and I do not smoke. If you purchase multiple items, I can combine shipping, so please feel free to ask☆ Thank you for viewing my many products.
