Is the shaving head of your Braun Series 3 shaver due for replacement? With the Braun 21B Cassette, your shaver will perform like new again. Ideal for professional use in salons, barbershops, wholesalers, and other business environments where quality and reliability are essential.

Over time, shaver blades wear out. This can reduce shaving performance and may cause skin irritation. Braun therefore recommends replacing the shaving cassette every 18 months. This helps maintain powerful shaving performance and ensures a smooth and comfortable shave.

With normal use, millions of hairs are shaved within approximately 18 months. Replacing the Braun 21B Cassette helps maintain the performance of your shaver without replacing the entire device.

The black Braun 21B Cassette is specially designed for Braun Series 3 shavers and is easy to replace. Thanks to its precise fit, the shaving head connects perfectly to the shaver.

How to replace the Braun 21B Cassette

1. Make sure the shaver is disconnected from the power supply.
2. Press the release buttons on the sides of the shaving cassette. If your model does not have release buttons, carefully pull the cassette off.
3. Hold the new Braun 21B Cassette by the sides and click it onto the shaver. Please note: the new blades are sharp.
4. After replacing the cassette, press and hold the power button for at least 5 seconds to reset the replacement indicator.
