Green is suitable for grooming cats and dogs during the moulting period, and when you want to efficiently remove hair during the moulting period. Orange is a long-haired comb, suitable for long-haired cats and dogs. It can keep long hair without hurting slender hair, and clean it without waste. The combs are made of special plastic material, elastic and durable. Because it is soft, it will not harm the pet's skin. Comb through hair like a massage, lightly brushing to remove deep fuzz. Long-term use will not break. (But dogs and cats can't resist biting them) The advantage of the shell comb is the finger-like comb with the curved front end. The comb is soft and elastic (special material).
