No idea. I tried to find out from Braun: https://www.braun.de/de-de/male-grooming/stylers-and-trimmers/multi-grooming-kit/multi-grooming-kit-mgk3085 There is a link under "Maintenance" to "Find Multi-Grooming-Kit MGK3085 spare parts", but when you click on it, you get a runtime error. A poor performance by the Braun computer scientists...
