Style Series B3 is an easy-to-use battery-powered (2xAAA) beard trimmer equipped with a zoom wheel that lets you choose from 17 precise cutting lengths with precision and lightness. While the self-sharpening blades with Comfort Tip have been designed to feel supple against the skin and always give sharp results. Roll on the zoom wheel and choose freely in lengths 0.4 mm to 18 mm, you can easily loosen the cutting blades to clean your blades so you keep your beard trimmer clean and fresh longer.
