Wisecrafts’ Magickal Bath Salts start with a base blend of Salts, Baking Soda and Cornstarch. Pure Essential Oils are then hand mixed into this base to give just the right blend of scent to each recipe. All of Wisecrafts Naturals Bath Salts are highly scented so a little goes a long way. These bath salts are packaged in beautiful REUSABLE cobalt blue jars and come in 4oz. or 8oz. sizes.
