Review (1/5): Save your money.
What on earth was I thinking when I bought these? I think I am smart person, but it just never dawned on me that using a round slab of silicone to apply a foundation couldn't work. It acts like a squeegee. You put the foundation on, then grab one of these babies and pull it right off. I think they should be repackaged as make-up removers. That makes more sense.
