Remology’s 2 In 1 Expert allows you to groom with the utmost care and accuracy. This device comes with two interchangeable heads which makes grooming a breeze. Head 1 is a rotary blade head for trimming those hard to reach hairs in your nose and ears with no nicks, cuts or pulling. Head 2 is a detail groomer head for trimming beard, stubble, neckline and sideburns. A soft bristle brush is included for an easy clean, and the heads are washable and removable for a deep clean. This device is battery powered - 1 x AA battery (not included)
