These are great to hold the Summer and Winter Solstice Blends for Skincare Treatments. You just put a tablespoon or two in the bag, tighten it up and soak in water to enhance the water. It's also great for Manicure and Pedicure treatments, Just tighten the bags pretty well if you are using them in a pedicure tub so that the leaves and herbs of blend don't escape the bag.
