Two pack of super strong 4 oz shower steamers. Each one lasts about 4 showers. Ours are super strong because instead of just essential oils we use flowers as well. Our invigorating blend will get you ready for the day with menthol, lemon and basil. Place in the corner of the shower away from direct hits from the shower. They work best when the bathroom door is shut and the water is hot . This allows the blocks to steam. Each one is 4 ounces and this is for two steamers.
