Muhle 31K257 Ivory Resin Silvertip Fibre Synthetic Shaving Brush, 21mm

This is my first synthetic brush and I can say that it is of very good quality. The fiber is very soft and feels nice on my face. If you have never tried a synthetic brush before, you can probably find a makeup brush from your wife or girlfriend and get the idea (don't use those to shave with though!). The brush also dries very quickly and of course doesn't have an odor like some animal-sourced brushes. The biggest issue I have with this is that because it is hydrophobic, it does not really retain lather as well as badger hair, which is hydrophilic. If the lather is watery at all, it tends to slide down the brush and onto my hands. It also makes it hard to spread on my face or do much beard lathering. That said, it does have a good amount of backbone and doesn't flop as easily as badger hair.

I love this brush. It's very soft and produces more lather with less product than my silvertip and boar brushes. It also does not require soaking and dries very quickly. In two years it's held up great as my most used brush.
