Blue clippers perfect for pet grooming, with replacement blade and brush. Length: approximately 14cm. Charging is done via USB cable. An English instruction manual is included. I bought this for my long-haired cat, but I couldn't use it because the cat wouldn't stay still. Therefore, it's like new. The blade can be easily removed by pushing the tip of the blade with your thumb from the switch side. Please consider purchasing only if you understand that this is a long-term stored, used item. Please refrain from purchasing if you are sensitive to such things. Thank you for looking.
