The Panasonic Performance Hair Clipper ER-GC63 is a powerful tool for cutting hair and trimming beards at home. This washable men's trimmer uses a 45-degree blade edge forged from premium Japanese stainless steel to cut through even thick or hard hair with ease. An adjustable length dial works with two comb attachments to provide accurate trim length settings up to 39 from 0.5-20mm at intervals of 0.5mm* (*Cut to .5mm is possible when no attachment is used), allowing you to nail different haircuts and styles. With cord/cordless operation, you have the freedom to cut hair anywhere, at home or while traveling. To maintain the top performance of the clipper, rinse the blades after each use and replace them when they become dull, approximately once every 3 years with Panasonic WER9605.
