Size is M (see photo 7). There is a name written on the right ear, which has been covered with a permanent marker. The face shield will be wiped with alcohol and shipped as is, but please discard it if you don't need it. Overall, there is a feeling of use. Only noticeable issues are shown in the photos. There is one spot where the white paint on the front metal fitting is chipped (see photo 8). Other than that, there are minor scratches compared to a new item, but please understand that this is a used item. It will be wrapped in bubble wrap or other cushioning material for shipping.
