I believe this is an adult-sized neck warmer, but it was worn for one season by a late elementary school student. I've placed a measuring tape in the photos, so please refer to them for the size. Please note that the actual color may differ slightly from the photos. I don't see any noticeable stains, but please forgive any oversights as I am a private seller. Shipping will be via either Rakuraku Mercari Bin or Yu-Yu Mercari Bin. Please purchase only if you understand that this is a used item.
