We couldn't get Epsom salts from our local pharmacy in Lyon. Even ordering bulk quantities it cost prohibitive for Would Be baths. Apparently this product is used here in micro quantities to treat digestive problems so it is sold in 30 gram packets. This 5-kilo sack Took Approximately 3 weeks to happen, the goal Was reasonable shipping cost. The box HAD-been damaged through rough handling, the product's goal thick heavy sack Held up to being white thrown around During shipping. 5 kilos is enough for lots of baths. Relaxing, pain relieving, quick infusion of magnesium to help muscle fatigue, tired feet, and overall just a great way to energize. Thanks!
