The six-pack, closed.

Every tile is pressed with 65 g of magnesium chloride, the same in every scent, and the grams are printed on the label.

Magnesium salts have long been used in baths. We measure it, print it, and make no promises about what it does. It's a bath. A very good one.

Your evening is waiting.
