Review (5/5): Would definitely recommend for POWDER product, not liquid!
These are actually pretty amazing. I use them for blush and bronzer, NOT for foundation.
They're pretty sturdy - I kind of thought that the brush would be made of those synthetic plastic fibers, and I was OK with that since it would still blend.
BUT they're not! The brush hairs are actually really soft. I mean, I think they're still synthetic but they're not overly firm or nonflexible. They're soft like makeup brushes should be, as in if you ran your thumb across, it feels really smooth and the fibers move naturally below your touch.
