Our salt cube scrub is a bubbly exfoliant that is perfect for exfoliating heels and elbows. Because of its exfoliating power, we do not suggest using this product on your face. For a gentler exfoliant, your may prefer our sugar cube scrub. The individual cubes are the perfect size for one-time use and will fit easily in your hand. Because of their size, these cubes are great for use while traveling.
