Convenient, easy-to-use pet nail clippers use QuickSensor™ technology to show you exactly where it's safe to clip! Clipper’s advanced design senses your dog's quick, so you can avoid a clip that will cause pain and bleeding. A red light appears when you're within the quick, yellow when you're on the border, and a green light appears when you've cleared your dog's quick, eliminating guessing and pain. Non-slip handle. Stainless steel blades. Requires two button-cell batteries (included).
