Had surgery recently. Came home with a wound dressing and drain, so unable to shower. Included in my take home supplies were these washcloths. Sterile ('till opened) 8x8 washcloths, soaked with purified water, cleanser, Aloe, vitamin E, moisturizers. Can be used as is or warmed briefly in a microwave (my choice).
Big plus - no water needed. One's enough for a good overall rub down.
Apparently available retail - sageproducts.com - and made in the USA.
