These bombs are as natural as you can get.  Made with aluminum free baking soda, citric acid, Epsom salt, arrowroot powder and sweet almond oil.  The only ingredient that's not natural is the fragrance oil, but all of my scents are made in Canada and are phthalate and paraben free.  You can also order 100% natural bombs with an pure essential oil for fragrance.  Most of my customers order an assorted bag of 20 bombs for $25
