The Wahl Vari-Clip Hair Clipper Set is a mains-operated adjustable 12-piece hair clipper kit, where the clipper has a thumb adjustable taper lever to vary the depth of cut. The four attachments each give a different length of cut to make it a simple job to get your preferred style. The high carbon steel blades just require an occasional oil, included, to keep them cutting smoothly. The set also includes a pair of scissors, a barber's comb, clipper oil, a blade cleaning brush, plus a soft pouch to store it.
