This callus remover for feet comes with three quartz sand roller heads: rough for stubborn dead skin, medium for rough dead skin, and fine for daily foot care. You can choose the right one for your needs. The rollers spin 360 degrees at an amazing 40 times a second, covering a 300-degree wide angle to gently buff away hard skin on the heels.

The device has two speeds: 1700 RPM/min for daily care or less severe calluses, and 2000 RPM/min for severe calluses or dead skin. Switching between speeds is easy with the touch button.

The kit is rechargeable and comes with a charging cable. The built-in 1200mAh battery fully charges in 3 hours and provides up to 60 minutes of use. The LED display shows the battery level and when to charge.

The device is designed to be safe and gentle, removing calluses and dead skin without damaging healthy skin underneath.
