These reusable wraps are made from 100% cotton to make rice bags which hold heat or cold. I double stitch all seams for durability. The rice is scented with pure peppermint essential oil. Peppermint essential oil is traditionally used to help open stuffy sinuses and soothe upset stomachs. Of course, peppermint also gives it a holiday scent! The bags measure approximately 5" wide and 18" long and are filled with around 2 pounds of food grade rice. They mold nicely to any contour to deliver heat or cold as well as relaxing aromatherapy. Throw it in the microwave for a minute or two and enjoy up to a half hour of relaxing heat. Great for achy joints, tired muscles, neck tension or menstrual cramps. Or, throw in the freezer to enjoy a cooling neck wrap or to apply cold to injuries. To keep the scent for as long as possible, we recommend keeping it in the recoverable bag it comes in so the oils do not evaporate when not in use. I'm always happy to discuss custom orders- message me if you'd like a wrap made with different essential oils, or are looking for a different color or pattern. We offer a variety of healthy and natural body care products in our store!
