Maintain your best shave with the Braun Series 8 Replacement Head, recommended to be replaced every 18 months. This shaver head is compatible with all Series 8 electric shavers.

Replace the foil & cutter block every 18 months to restore your shaver to its best performance. The Series 8 shaver head offers powerful yet gentle shaving with 4 synchronized shaving elements for a precisely close and gentle shave. Replacement is simple with an easy click-on attachment. Crafted with quality in Germany, this shaver head is also compatible with all Series 9 shavers. Dimensions: 2.0cm (H) x 4.0cm (W) x 3.5cm (D).
