Compatibility: Replacement blades for Braun Series 7 electric shavers F/C70B-3, F/C70S-3 Note: This product is not an official Braun product, but a replacement for Series 7 shavers. However, its performance and usability are fully satisfactory. Product Features: The metal mesh cover of the replacement blade has over 2000 nano-level micro-holes, which catch hairs growing in any direction without missing any, and shaves them thoroughly from the root. This provides a deeper and gentler shaving experience than before, delivering a perfect shave.
