I wanted to get a manchurian badger brush but Simpson's prices were too much for my budget so I ordered a Oumo brush instead that claimed to have their manchurian knot which I believe is among their best grades. Is there any quality difference between the badger hair used between the Oumo and the Simpson? After all I figured that manchurian badger hair comes from China anyway so the place of origin for both makers are the same general area. Am I off base ?
