Black Fibre. Innovative into the future: with its dark colouring, softness and quality, this synthetic fibre is the sustainable answer to the questions of our time. Black Fibre resembles natural badger hair, but is more robust and durable, and at the same time slightly softer at the tip than the natural material. The MÜHLE manufactory’s very own innovation makes it possible to whip up a particularly creamy shaving lather. The amount of effort required for cleaning and drying is significantly lower.
