Nail file, straight, black SINCERO SALON, 180/600

One side of this nail file is medium soft (180) and other side is soft (600), that's why it works better to trim natural nails with your desired shape or length. Nail File is made with top quality adhesive tape and emery board materials. This nice, sturdy & durable nail file provides you a comfortable nail doing experience. HOW TO USE: Wash your hands, thoroughly dry them. Choose a nail file. Try using a file with a softer grit of around 180-200 to keep the edges from looking rough or scraggly. If you want to use a separate file to finish your nails, choose one with a high grit, around 300-600, to get the smoothest edge. Coarse grits, around 80-100 grit, should only be used with acrylic nails. If you use them with natural nails, they will tear up your nails. Hold the file parallel to the side of the nail. Hold the file parallel to the side of the nail when beginning your filing. This will prevent breakage. It’s important to file your nail from the side to the center in one direction using a fluid motion. This will ensure that your nail is smooth, and not jagged.
