These hand and foot pumice stones are lightweight and measure a very manageable 5 x 2 x 1 inches. You won't get hand cramps or feel like you're getting a workout when you use them. We designed them so that everyone can treat themselves to a relaxing mani-pedi wherever and whenever with ease and comfort.You're in charge of the pressure. The unique, upgraded design of these foot scrubbers comes equipped with two coarseness levels: Purple (coarse) and Lavender (medium). The ridged, coarse side is ideal for more stubborn skin issues, and the fine, smooth side is great when you want more gentle pressure.You might have been frustrated in the past with similar pumice stones that fell apart after a few uses. That won't be a concern with these. Unlike other scrubbers, these will not shed or crumble easily. Even when you have to use a lot of "elbow grease." They're designed to last and be used over and over.
