This nail file is built with a stainless steel filing surface set into a contoured, easy-grip handle sized for small hands and small paws alike. The curved shape is designed to follow the natural line of a toy breed or puppy nail rather than a straight edge, so the file glides along the nail rather than catching on it. It is intended for use after trimming, smoothing any rough edges or burs left behind on the nail tip. To use it, the toe is held firmly while the file is drawn in one direction, from the back of the nail toward the tip, following the nail's contour. A handful of strokes on each side of the nail is generally enough to leave the surface smooth. No batteries, charging, or assembly are required, and the tool is ready to use straight out of its packaging.
