Whether it's a sore pulled muscle from the gym or yoga, an ache or pain from overwork, Spa Girl uses her trusty back belt to provide the needed heat or cold therapy to heal in a healthy way. The peppermint and lavender flowers sprinkled inside release a delicious aroma to uplift and delight your senses. Microwave and let the warm heat therapy penetrate deep into sore, tight muscles. Chill in the freezer and let the cold therapy soothe sports injuries or cool you down on hot summer days.
