The Standard Nail Filer & Buffer (100/180) is a versatile tool essential for both manicures and pedicures. Designed with a dual grit of 100/180, it provides effective filing and buffing for natural nails as well as nail extensions. The 100 grit side is perfect for shaping and refining nail extensions, while the 180 grit side is gentle enough for smoothing and perfecting natural nails.
