These steamers will wake you up with a citrus blend of orange, spicy ginger and grapefruit and a small amount of menthol crystals to boost the fragrance. A natural way to alleviate allergies or congestion, these are perfect for an aromatherapy experience while you shower. Steamers are like bath bombs but sit on your shower floor to fizz and release a scent. Each package contains four steamers weighing about 2 oz. each. To use, start shower to get moisture in the air and slightly wet the steamer to activate. Put on the floor of the shower or in a place out of direct water so that it can release slowly. Each steamer is intended to be used for one shower, but may last longer. *external use only. Steamers are not meant to be used like bath bombs in a tub of water as they have heavy fragrance/essential oil. Ingredients: sodium bicarbonate, citric acid, menthol crystals, citrus essential oil blend.
