This battery-operated trimmer features a protective cap, outer blade, outer blade frame, inner blade, joint, on/off switch, body, and a battery cover. To use the device, slide the switch upward to turn it on and carefully insert the tip of the outer blade into your nostril or an ear hole. Additionally, the trimmer is easy to maintain.
