Each of our Lush Amazon Rain bath bomb products are made by hand at our manufacturing facility in Idaho. We start by small-batch mixing our proprietary blend of premium vitamin- and antioxidant-rich ingredients. Each bath bomb is then carefully hand-packed and left to cure for just the perfect amount of time. They are then wrapped, boxed and ready for you! Producing small batches as needed helps us ensure you are getting only the freshest, most effective product.
