This is a size M black supporter from Wacoal CW-X, perfect for knee support. Please note that this is a used item. I've used it about 3 times, and washed it each time. I'm selling it because the size doesn't fit me. I'll say it again, this is a used item, so please refrain from purchasing if you are concerned. - Brand: Wacoal - Size: M - Color: Black Thank you for looking.
