These pumice stones come from Mt. Shasta in California and are sold to you exactly as they are found in nature. Pumice is formed when hot lava mixes with water causing it to harden. The result is a porous and abrasive stone, ideal for gently scrubbing away dead skin.
Stones measure approximately 3.5" x 3.5" x 2" and weigh between 3.0 - 3.9 oz.
