All plastic free deodorant.
This natural crystal deodorant lasts way longer than you'd expect. Made from a solid block of mineral salt (Potassium Alum), simply apply to wet skin (after a shower is ideal) or wet the crystal before applying to dry skin. It leaves an invisible layer of the mineral salt on your skin (so no white marks!) which inhibits the bacteria that cause odour.
The unscented deodorant comes in a cardboard box, so no plastic packaging with this product.
