This is an electric knee blanket from YAMAZEN. It's reversible, with flannel and poodle touch sides. It can be washed at home. Purchased in the winter of 2018. It cost around 4900 yen when new. I used it between a blanket and a futon. There are no noticeable stains or scratches, but the poodle touch side has some small white pills. (Please check the photos.)
