Easily change speed and direction as you go, and switch the grit as needed with four interchangeable buffer pads for newborn nails to coarser toddler claws. An always-on LED task light eliminates shadows for more focus and precision, day or night. Once you've nailed their mani/pedi, store everything in the secure case with your go-to pad in place, so you can grab and buff with one hand when the next snag strikes.
