Kent 87T 2 1/2" 70mm Gentleman's Folding Pocket Comb, Flexible Men's Beard & Mustache Pocket Comb. Hand-Made Cellulose Acetate, Saw-Cut and Hand Polished. Kent’s handmade combs are saw cut, and then hand polished and buffed to create soft rounded teeth that will not damage your hair or scalp. They are made from cellulose acetate, a non-petroleum based plastic derived from plants that has been found to create less static in hair. These teeth run smoothly through the beard and stimulate the natural oils inside the whiskers as they're combed. These oils encourages the whiskers to do as told. A non-handmade comb is known as an injection molded comb. They have razor sharp teeth which damage the hair cuticle, and scrape the skin. These type of combs also feature tiny ridges, known as "mould marks" which scratch and snag your beard and moustache. Get the right tool for the job.
