This is an abus helmet. Size L, 59-61cm. I've used it for about six months, so please refrain from purchasing if you are concerned about that. After use, I stored it on a shelf, so it may have some dust. I will clean it before shipping. The box is available, but it has scratches and dirt. I can include the box for an additional 1000 yen. If you purchase without requesting the box, only the helmet will be shipped.
