Product Highlights -10pcs in each pack -Easy to use -Fine grit allows precise filing without overfiling How To Use It Swipe the tips of the tweezers across the nail file about 3-4 times. Press the slant tip down into the file, then flick your wrist to drag the blades quickly across the file. The motion you'll use here is very similar to sharpening a knife on a whetstone. Repeat this motion several times. Tip: If your tweezers come to a sharp 2-sided point, rather than a single slant, carefully run the nail file along one outside edge, then the other.
