Washable design, the ER-GC55 adjustable-length hair clipper. - Brand: Panasonic - Model: ER-GC55 - Features: Washable - Power: On/Off switch - Settings: 0.5-10mm length adjustment - Accessories: Oil, brush, charger Thank you for viewing. I purchased this new last month and used it once, then washed it. Therefore, there is a slight feeling of use. I believe the operation is problem-free. All original accessories are included. The warranty is attached to the instruction manual, but I'm not sure if it's valid if purchased through Mercari. Therefore, please assume the manufacturer's warranty is not applicable.
