Made of: Natural lava stone + cotton hanging loop.
Stones are both porous and abrasive making them perfect for scrubbing rough skin on feet, heels, and elbows. Can be used to remove hair or pills from fabric (gently), and even clean stubborn water rings in your toilet. Soak feet in the shower or bath for a few minutes until the skin is soft. Wet stone and scrub rough areas for a few minutes with light pressure. Moisturize your feet after use.
