I purchased this last year for a school trip and used it, but I'm selling it because I've grown and the size no longer fits. ★It feels like a women's M size. Photo 10: There's a 1mm-sized shiny spot on the front of the left arm. Photo 11: There's a 2mm x 3mm-sized shiny spot on the back of the left arm. Photo 12: There's a 3mm-sized white spot on the front, slightly to the left of the center. In reality, the shiny spots are black and glossy. The white spot in photo 12 is not as noticeable as it appears in the photo. Please understand that this is a used item. Thank you.
