I used the Body Shop Maca Root cream (tub) y'day.
Lathered well, used too much product actually. Second/third passes were ok, with the lathering appearing thinner (brush only loaded from the tub once, in the beginning). Face lather, of course.
The surprising thing at the end was that the knot took considerably more time to clean than with my other brushes. It's center was full with cream which kept generating thin lather as I was cleaning with water.
Not the most predictable of brushes by any standard, but certainly capable and interesting. My offer was $39.xx or $44.xx if I remember correctly, and was naturally accepted.
