6E emery boards are professionally designed for shaping and maintaining nails. Emery board use will provide smoother, healthier and stronger nail texture whilst maintaining the natural composition of the nails. Our emery boards also protect any damage such as brittleness or broken edges. How to use Always apply on clean and dried nails. Rub across in one direction, until you get desired shape and smoothness. Always shape the nails to the shape of your cuticle and for toenails rub the file in straight direction. Precautions: Never apply on damaged or sensitive nail. Don’t rub too hard always be gentle. Bending of emery board can result in damaging the board. Always keep emery board dry and clean. Always wash your hands and wipe emery board before and after use for safety and hygiene.
