"SHADY FALSE ADVERTISING. Purposely misleading customers. Claims USP grade in the title but not at all. I even contacted Amazon and after some time they admitted the product is not usp grade and just a “marketing claim” ew"

This is the first time I have ordered Epsom Salt Soak from the Amazon Basics brand and I plan to order more bags! That is how happy I am with this soak! The bag is easily resealable, which is a huge love for me! The salt is in tiny granules and feels so nice in the bag unlike other epson salts I have bought in the past that are hard. I used this in my little girls bath to help her feel better while battling the flu. This Epson salt soak is a winner for sure!judith l
