Brand unknown. This wig was purchased at a used goods store as a 6-7 inch size. It's a bit small, so it might be difficult to put on a Yo-SD. It fit on Tinyfox and Shoushoudoll dolls. Slightly messy. Since the original packaging, inner paper, and wig net are missing, I will substitute with something else and pack it a bit compressed. *Please refrain from cancellations or returns due to reasons such as the size not fitting or being different.*
