These pumice stones for hands and feet are lightweight and measure a very manageable 5 x 2 x 1 inches. You won't get hand cramps or feel like you're exercising when using them. We designed them so everyone can enjoy a relaxing manicure and pedicure anywhere, anytime with ease and comfort. You're in charge of the pressure. The unique, improved design of these foot scrubs comes equipped with two coarseness levels: purple (coarse) and lavender (medium). The ridged, coarse side is ideal for more stubborn skin problems, and the fine, smooth side is ideal when you want gentler pressure. You may have been frustrated in the past with similar pumice stones that fall apart after just a few uses. That won't be a problem with these. Unlike other scrubs, these won't flake off or crumble easily, even when you have to use a lot of elbow grease. They're designed to last and be used again and again.
