I have not found a corresponding replacement trimmer here at Galaxus. However, according to the Philips website (https://www.philips.ch/c-p/NT5650_16/nose-trimmer-series-5000-nasenhaar-ohrenhaar-augenbrauen-detailtrimmer/zubehor), these should be available (https://www.philips.ch/c-p/CP1972_01/nasenhaartrimmer).

A larger device would probably be more effective for this ;) Thank you for your comment. I have passed this on to the relevant department for correction and it will be dealt with as soon as possible.
