Regular teeth. Chrome. USE: For combing and tidying the coat and untangling knots. COAT TYPE: All types. FOR: Medium dogs and cats. SIZE: 7" X 1.2" These combs have a chrome coating on the teeth that prevents them from rust, but more importantly they provide a better slide during use to avoid friction, frizz or unnecessary hair breakage. The regular tooth is recommended for opening the coat and eliminating tangles, even eliminating shedding hair thanks to its resistance. It has a wider and a narrower part as needed.
