Acrylic Boa Sheet, 100% Acrylic 140 x 200 cm size, Antibacterial and Odor-Resistant Treatment, Elmano Nishikawa. Unused, but stored at home for a long time. The box shows signs of aging. From what I can see from the top, there are no visible stains, but since it hasn't been opened, I haven't been able to check the entire sheet. If purchased, I will remove it from the box to save on shipping costs. In the unlikely event that there are any stains, I apologize, but please refrain from canceling the order. Thank you for looking.
