Gillette Mach3® - Yellow. At home everywhere, with an open mind for new worlds and experiences: The cosmopolitan is the role model for the development of this modern series with its contemporary, elegant design. Its special appeal is achieved not least by our characterful materials such as horn-coloured or black high-grade resin. For the natural materials MÜHLE has chosen olive wood in warm shades and bog oak as a darker contrast. Selected sections of wood from trunks up to 3,000 years old are used. Simple, high-quality chrome rims accentuate the beautiful surfaces of the handle materials. Like many of our series, KOSMO is available in the hair grades silvertip badger, fine badger and vegan 'Silvertip Fibre'. The brush heads can be unscrewed and replaced with ease.
