Muhle’s Kosmo Fine Badger Hair Black Shaving Brush is made from highgrade resin with chromeplated metal highlight. The highgrade resin is a highquality synthetic material. Fine badger is softer than pure badger, but somewhat firmer than silvertip badger. The hairs are light grey in colour and feature the dark stripe or band typical of high badger hair qualities. This natural hair material is extremely wellsuited to wet shavers who value the softness of badger hair and want to achieve a massage effect.
