You can get it from supermarkets, guardian, watsons, Shopee and Scoop (Scoop has two kinds if I’m not wrong - one is good grade, another one is not, which is usually at the body scrub, bath bomb section). Just take note. https://www.guardian.com.sg/esentiel-epsom-salts-375g-117758.html?page=1 https://scoopwholefoodsshop.com/products/epsom-salt-500g
