Braun Series 3 Combi 30b Foil And Cutter Replacement Pack (7000/4000 Series)
Braun replacement foil & cutter blocks help to maintain your shaver’s maximum performance. Braun recommends changing your shaver’s blades every 18 months as the cutting parts will gradually wear out over time, and your shave may become less close and comfortable. After replacing them you get back 100% of your shaver’s performance.
