Yamato Michi Light Alpha Sleeves Size S Light Gray Purchased new from the manufacturer's official website last season. Used only about 3-5 times for city runs of about 5 kilometers. I didn't use them much because the size was too small. I'm selling them because I don't think I'll have a chance to use them in the future. I think they are very clean, although I am a layman. Perfect for the coming season. Please refrain from purchasing if you are nervous, as these are used items.
