I purchased this at a chiropractic clinic about three years ago. I bought two, and this one is a new, unused item that I've been storing. Please refer to the second image for the size and other details. Unisex This is a great help when you have a sudden lower back pain. I opened it to take the photos. Note: To reduce shipping costs, I will ship it without the outer box, so please be aware of this. The outer box will not be included.
