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 & basil. Place in the corner of the shower away from direct hits from the shower. They work best when the bathroom door is shut & the water is hot . This allows the blocks to steam. Each one is 4 ounces & this is for two steamers.
