The Bona Fide Beauty™ Czech Glass duo nail file set includes a bow-shaped, ergonomic file designed to effortlessly shape your nails. It also comes with a rounded straight glass nail file to shorten, shape, and seal the keratin layers of your natural nails to prevent splitting and tearing. This uniquely shaped nail file has its grits along the inner grooves on both sides, providing an ergonomic grip on the file. The shape allows for easy shaping and filing in the difficult to reach corners. Compared to other nail files, this ergonomic design has a larger surface area for a comfortable grip. When filing, the curved corners follow along the natural nail curve, thus providing a precise, comfortable, and effective filing experience. Highlights: Set Includes: Bow Ergo File and Rounded Straight Glass File Grit: Fine grit along on the inner grooves Length: 3.3 in (85 mm) Thickness: 0.1 in (3mm) Case: White Sleeve How to Use: STEP 1: HOLDING THE ERGO FILE Hold the ergo file with either of the inner grooves facing outwards. STEP 2: PLACING YOUR NAIL Place the nail you want to file in the inner groove. This is where the nail filing grit is etched! STEP 3: FILE WITH THE CURVE To start shaping, file along the natural curve of the groove in small one-way strokes to get a nice rounded and smooth free edge. STEP 4: WASH, MOISTURIZE & STORE Once you're happy with the shape, finish off your manicure by rinsing your nails and your nail file under running water. Pat both dry with a towel & apply cuticle oil or hand lotion to your nails.
