Yaqi 26mm Tuxedo knot

Yaqi make very good brushes - they're a manufacturer and make brushes for numerous customers under different names. I have that brush and it's a good performer. Whilst synthetics dont break-in in the conventional sense, I find that the knots do loosen slightly after a few uses. A few brushes I was initially unimpressed with have turned out to be good performers.
 
Nice brush, seen that one featured on a few of the wet shavers channels over on YouTube.

I have the Yaqi Mysterious Space brush (which has this same knot) and it's my favourite brush.
For quality, value for money, and performance wise, in my opinion Yaqi are unbeatable.
