If you feel more secure with a scissor-style grip, then these scissors are a great choice. Also, if you don't like to file your nails, scissors will give you a smoother cut than nail clippers.
1. Wash your hands in warm, soapy water or use after a shower or bath. Clean, softened nails are the goal.
2. Starting at one edge of your nail and finishing at the other end, carefully cut to the length and shape you'd like.
It's best to keep your scissors in a dry environment. If they get wet, dry them with a clean towel. You can also keep the cutting edges clean by wiping them with a towel after use. Swabbing the blades with rubbing alcohol and allowing them to air dry (while open) can help to keep them bacteria-free.
