Updated BTArtbox Rechargeable Nail Drill with 35,000 RPM Brushless Nail Drill Handpiece Updated BTArtbox Rechargeable Nail Drill comes with superior 35,000 RPM Brushless Nail Drill Handpiece that allows you to "salon-like nail art at home" and do your own manicures like a pro. Functional, Low heat, low noise, low vibration, powerful and smooth, it's an essential tool for nail-care veterans and newcomers alike. It can be used to file and shape of various nails. It works much more quickly than a standard nail file, which is why it’s an especially important tool for shaping and maintaining nails. It also works well for fixing cracks in acrylics, removing lifted acrylics, filing nails before applying gel or acrylic nails, buffing natural nails, fixing cuticles, and smoothing calluses or hardened skin on your hands or feet. Excellent condition, like new! I purchased to try, not able to do my own left hand.
