If you’re out and about, and a hot water bottle or a wheat bag isn’t practical then these hand warmers are a perfect solution. Heat up in minutes, and stay hot for hours, perfect for providing heat to the areas that need it. Tuck into your pocket, waistband, under your bra strap, in your sock, up your sleeve, or hide them in your glove…so many possibilities for getting warmth to the muscles that need it!
