This is a Panasonic ES9610 replacement blade, an integrated type. One blade from the front lower part of the replacement blade has come off. If used with care, it can still be used as a 5-blade shaver without any problems. Please understand this before purchasing. Panasonic ES 9610 replacement blades are compatible with ES-L650D, L650U, L670U, and L690U models, providing a comfortable shave. Thank you, and I look forward to our transaction.
