Your Deluxe U-Clip Pet Clipper will come equipped with everything you need to start grooming at home including a How-To-DVD! The Wahl #30-15-10 Standard Adjustable blade adjusts between different blade lengths via a taper lever on the side of the clipper similar to ones traditionally used for human hair. If you have experience clipping hair, this will be a breeze. If you don't, no worries, the 3 different lengths give you a lot of flexibility to clip with. Not only does your Deluxe U-Clip come with an easy-to-use adjustable blade, it also comes with a series of guide combs that give you even MORE flexibility in your cutting lengths. If you want to leave the fur a little longer on your pup's legs but keep it shorter on his head, attachment combs can help you do that. Other convenient additions include a storage case, grooming scissors, a comb, an apron!
