This is a Hera puff.

I've tried various products, but the puff on this one adhered well to the skin. I bought two for about 5,000 won, which is a bit of a burden, but I tend to collect them and wash them once a month. My makeup routine is to first moisturize the puff with a mist, then pat on foundation, and it absorbs well. Oh, how do you guys use yours?
