Shower Bombs are the newest thing in aromatherapy-- they combine the benefits of essential oils with the steam from the shower. My bombs are crafted with Menthol, as well as Eucalyptus, Peppermint, Rosemary, and Cypress essential oils and fizz and foam when the shower water hits them. Simply place the steamer on the shower floor, off to the side or hang from a mesh/organza bag from your shower head. Each bomb is wrapped individually in a tray that can be used to help them last longer in the shower. 50g each
