This pumice stone made from natural volcanic rock effectively removes calluses, softens heels and leaves feet soft and smooth. 100% natural and sustainable, its porous structure gently exfoliates without damaging the skin. To use, soak feet in warm water, gently rub rough areas, then rinse and moisturize after use. Versatile, it can also be used on elbows or hands and is a zero-plastic alternative for regular home care.
