Remove unwanted hair from nostrils and ears safely, quickly, and easily with the ER415SC Personal Groomer. All Panasonic Groomers are designed with a safety cone, which wraps around the blades to prevent them from coming in contact with the skin. The blades themselves are made from hypoallergenic stainless steel so they will hold their shape and resist rust. A non-slip grip wraps around the groomer so it is easy to hold and maneuver. The cap will also attach to the bottom of the groomer to extend the grip. For easy maintenance this unit rinses clean under running water. Runs on one AA Battery. (not included)
