Unclip the clasp at the bottom of the pliers by squeezing the handles inwards firmly.
Grip pliers firmly & cut nails straight across.
Do not cut into corners of the nail as this may cause ingrown toenails.
Use an emery board or nail file to smooth nail tips, preventing sharp edges & snags.
Re-clasp pliers by firmly gripping the handles as if cutting then push clasp back down until it "clicks in".
