Unfortunately I can't give you more details on this item as the one I received was too small for my wrist and was digging into the crease between my thumb and finger from where you put your thumb through. After figuring out away to decrease the irritation from this problem with a bandage and cotton ball I love it. The amount of pain I have in both of my hands is a serious problem and this product eliminated about 95% of that on the right hand and I was even able to get a better night's sleep. If I am able to find these for both of my wrist in a larger size I will be buying them as soon as I find them.
It worked great. It relieves the pain in your hand if you have carpal tunnel or arthritis. I bought the size s/m fits just right. But for a women if you have a med /lg hand you need to get the larger size.Tends to run small.
