The Philips nose trimmer series 3000 comfortably trims nose, ear and eyebrow hair. The new PrecisionTrim technology & the Protective Guard system have been designed to provide an easy and efficient trim without all the pulling and tugging. Easily reach and remove unwanted nose and ear hair efficiently. Ensure your nostrils are clean before use and carefully insert the trimmer inside your nose no more than 0.5cm and slowly circulate it. When trimming ear hair, ensure ears are free of wax. For brow hair, slide one of the two combs (3 and 5 mm) into the grooves and trim with light pressure moving against the hair growth for an even eyebrow trim to the length you want. Fully washable for easy cleaning. This trimmer runs on one AA battery that is included in the box, so your trimmer is ready to use right away.
