The BIG masow electric callus remover uses TYPE-C charging, making charging faster and more convenient. You don't need a special charger; you can charge it with the same cable as your smartphone, allowing you to take care of your feet anywhere. After a full charge, it can be used continuously for about 1 to 2 hours. You don't need to bring a separate charger for business trips or travel, and you can continue salon-quality care even in your hotel bathroom. 【2-Speed Adjustable High-Rotation Motor & Clear LCD Screen】The BIG masow electric callus remover is equipped with a high-rotation motor and offers 2-speed adjustment.

To suit different skin sensitivities, three interchangeable grinding rollers are provided: fine, medium, and coarse, allowing users to choose the optimal care intensity for their skin type. Additionally, a grinding roller protective cover and cleaning brush are included, preventing impact and dust during storage, as well as eliminating the risk of accidental operation and the worry of shavings scattering on the floor. 【LED Illumination & IPX6 Waterproof】Bright and even light makes care easy even in dark places. The BIG masow electric callus remover has LED illumination, allowing you to clearly see even the details of your skin in environments with insufficient light, such as during power outages or on cloudy days.
