[Soft & Safety Confident Trim] The filing pad on the electric baby nail file is composed of 600-mesh micro-silica sand. After 40 model optimizations, we have improved it to a safer version ever. Furthermore, due to the durability of micro-silica sand, you don't need to change the filing pad often, which is 5 times more durable than ordinary ones. It also features an automatic over-pressure stop mechanism for extra safe filing. [Rechargeable Baby Nail File] Built-in high-capacity rechargeable battery, no need to replace the battery. With the included Type-C cable, it can be quickly charged in 1.5 hours and work continuously for 130 minutes. It only needs to be charged 4 times a year. [Infinitely Variable Speed Protection] The stepless variable speed lever design with 90° free rotation makes it easy to adjust to the best speed with just a thumb. Unlike the 2/4-speed mode version, high speed will make the skin warm, but slow speed doesn't have enough power, making the baby lose patience.
