I was attracted to this brush not because of Pixiwoo but because the size of the head and the short tuft for a stipple seems to be more unique for a stipple brush. It's soft and I like it a lot for cream brush . . .
However, the second or third time I washed it, a lot of the darker hairs were pulled out to the level of the white hairs. I have a LOT of stipple brushes in all price ranges, from MAC and Laura Mercier to ELF and Ecotools and none of my stipple brushes ever did that so quickly. Maybe I got a bad lot. Maybe not.
