Filled with crushed walnut shells. You can empty the sock, wash it and put the shells back in the sock. Great gift idea!!
Why do black walnut shells make the best hot socks?
Not wanting to be wasteful, a thrifty craftsman grinds leftover black walnut shells and transforms them into a soothing hot pack. It’s natural, eco-friendly and retains heat just as well as corn (and you’re not wasting viable food).
Note: color may vary as well as the dimensions.
