These volcanic stones are full of iron, magnesium, and other minerals pushed from the earth's core as lava.  They are great for removing dead skin as they are naturally uneven and full of holes as the lava settles and cools.
 
Every stone has a different shape and colour as they are truly naturally occurring stones not changed by synthetic ingredients. 
 
Use it after a warm bath, shower, or foot soak; remove the dead skin in a circular movement.
 
Aftercare:
Always rinse the stone after use.
Let it dry completely between use.
