Directions, In the shower: Place cube piece on shower floor . The cube will begin to dissolve and release wonderful, potent essential oils into the hot shower steam. Close door and use hot water for stronger scent. If cube does not melt completely, let dry and reactivate with 2-3 drops of water during next shower. DO NOT USE STEAMER AS BATH BOMB AS ESSENTIAL OILS ARE STRONGER. DO NOT PLACE SHOWER STEAMER DIRECTLY ON SKIN OR EYE LEVEL.
