Another for the collection:
At 42 euros delivered, an expensive 21mm knot synthetic brush. Very nicely made and presented, it lathers well and is comfortable to paint it on. Quite a stiff springy brush. It has some likeness to the appearance of silvertip but it doesn't perform like one. The tips are prickly when you attempt to lather with circular motions - more like pure badger than silvertip. If you have scruples about using animal hair this is a practical alternative but lacks the luxury shaving experience of the real thing.
I'll post a review in my Shaving Brush Blog soon.
