This is a genuine replacement blade that came with the Braun Series 9 Pro+. Due to an initial malfunction with the main unit, I had it replaced, and the new unit also came with a blade, so I have a spare. I used it only a few times, and I cleaned it with an alcohol cleaning machine after each use. It's used, but in good condition, and I don't want to throw it away, so I'm putting it up for sale. (I plan to use the blade currently on my shaver for 18 months, so I'd rather someone else use this one in the meantime.) Braun Braun Series 9 Pro + Series 9
