You can shave yourself smooth for 3 years, thanks to the included shaving cassette of the Braun Series 3 3040 Wet & Dry + Braun Cassette 32B. After 18 months, the shaving cassette is due for replacement. The electric shaver has 3 different shaving elements, consisting of 2 shaver foils and a middle trimmer that lifts up the beard hairs prior to shaving. The shaving elements move independently, so you can follow the contours of your face. In addition, the electric shaver has a fold-out precision trimmer to tidy up your sideburns. The electric shaver is waterproof, so you can choose a shaving method that suits you; dry, wet, or in the shower. Clean-shaven now? Simply rinse the electric shaver head under the tap.
