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 immunity blend will allow you to breathe in essential vitamins & natural ingredients known for their beneficial properties. 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. Immunity Blend With Elderberry, Super Strong Shower Steamer Block, Vitamin C & Zinc 2 Pack By Diva Stuff
