Vie-Long hose hair shave brush
The brush handle is wood with a chromed metal ball at the knot. The metal ball is a non ferrous metal so it will not rust. It is best suited for small to medium sized hands . If you have large hands, I would look for a different brush.
I have used the brush on creams, croaps, and hard milled soaps. It works best with creams. It does retain water well and does create a good lather so long as you don't use hard soaps.
It's lack of backbone when wet makes it difficult to use when compared to my Simpson T 3 trafalgar synthetic or my Omega boar brush. If my boar brush was an 8 out of 10 for backbone and my Simpson was a 6, the horsehair brush would be a 1 or 2.
It works o.k. for painting on lather to the face but is a poor performer if you want to work the lather into your stubble to help prepare for the shave.
I think this brush could be very good if Vie-Long increased the density of hair and the knot size to 26 mm. What makes my Simpson T 3 stand out is the density of the hair they pack into the knot while still maintaining a softness with excellent backbone.
This horse hair brush would be excellent if they did this and then it would truly fall into a good balance between a boar brush and a badger brush.
As it is now, I would not recommend this brush.
