Look at this great Tootsie Warmer I won from Martie Hanna , A Hair in My Biscuit’s Etsy shop. My Brother-in-law was visiting. He was in terrible pain from a wrist injury. I popped this in the microwave for a minute, he slipped his wrist in and got instant relief.Martie, you might consider making these mitt-sized for hands. He felt so much better. Please check out Martie’s great shop.
