Our professional hair clippers use professional cutter and sharp cutting edges to ensure precise and clean trimming, allowing you to easily trim hair, beards, sideburns, facial and body hair. Remember to add oil to the cutting unit before each use to prevent your hair from pulling. Multiple cutting lengths: The trimmer cutter is equipped with 4 different lengths of guide combs (1.5 mm / 2 mm / 3 mm / 4 mm), so you can easily adjust the cutting length according to your own needs. Our multi‐functional beauty trimmer can also be used as a facial, beard and body hair trimmer. It is very suitable for household use and hair care products. Easy to clean: The zero‐gap trimmer is easy to clean. You can rinse the cutting edges under running water or use the included brush to remove any hair residue.
