Why are our pedicure and body care tools made of Terra Cotta? Because in the Indian Subcontinent, there is no source of pumice. For thousands of years, women have instead used terra cotta, formed and fired in kilns. The benefits of terra cotta are numerous: they never wear out, they are not affected by cold or heat and can easily be sanitized or even sterilized in an autoclave. Plus they're handmade - with a natural ergonomic design.
