BRAUN Series 7 73S Shaving head

In the next 18 months, Braun razors will cut an average of 6 million hairs. This is accompanied by gradual wear of the shaving foils, which can lead to a less comfortable shave. That's why Braun recommends changing your shaver foil and knife block every 18 months to maintain peak performance. Take care of your razor and it will take care of you.
