They are doing a clearance sale on Muhle stuff. I guess they won't be carrying them anymore. I got a nice synthetic brush for cheap. edit: derp, I messed up conversion rates. In any case, I still got a great brush very cheap.
If you think 1 pound costs you $0.77, you're in for a nasty surprise I got a lovely 25mm Mühle synthetic from Connaughts for cheap, but I'm based in the UK
