Panasonic's ER421KC Nose and Ear Hair Trimmer has a special feature that lets you see paths where none (or few) have ever dared to explore before. That's because this nose and ear hair trimmer has a built-in LED light that illuminates the trimming area to help find hairs that need to be trimmed. Cut hair precisely and carefully with the ease and reliability of the new lighted cordless hair trimmer. It rinses clean and is fully immersible in water. Stainless steel blades trim hairs safely and carefully, and the blades stay sharp over time. The trimmer fits comfortably in your hand, and is ergonomically-designed to give you excellent control and more effective grooming. Look your best because everyone is watching.
