How to use:
Step 1: Insert trimmer slightly into nostril or ear by holding tool with thumb & forefinger. Place the cutting heads approx 1/5 inches into your nostril. (Be sure to clean area with warm water before use.)
Step 2: Squeeze handle to rotate the sharp interior blades, trimming visible hairs only. Maintain rotating movement during cutting to avoid unpleasant pulling.
(note 1: It might need some practices to adjust the operation for first uses - the trimmer is designed to trap hairs to cut. Once you're used to it, you will find it a much better tool to use);
(note 2: The blades are covered with 12 pcs metal fences, accordingly, it is safe enough to use);
Step 3: Clean tool after use with brush to remove excess hair from in between blades, or directly rinse it with water. Get it clean and dry and put it back into the original package. (note: please do not knock it against the desk to get rid of the hair)
Step 4: Please do not take the machine apart as it will affect the precision accuracy.
