Muhle Kosmo Silvertip Fibre V2
Revolutionary Muhle Silvertip Fibres are designed to mimic the qualities of the finest grade of badger hair brushes. Silvertip Fibres are animal friendly and will create a rich creamy lather from creams and soaps.
I started to use this brush a few weeks ago. I prefer it to plisson. The knot is ultra soft and the backbone is just right for my sensitive skin. On top of it, it makes lathering ultra easy and works even on "difficult" soaps. I have as well the 21mm knot but the 23 has the edge no question about it. Keep the 21 for travel :-)
