Etude Foundation Brush

This is a brush I received along with the foundation I bought at Etude. I like my foundation to apply thinly, so...

I tried applying it with a brush and it was totally my style. I'm not good at makeup, so it's hard to use this on its own, though.

I spread it evenly with this, and finish off the brush strokes by wetting a puff with water haha.

I didn't know this, but I heard you have to wash brushes and puffs frequently, too.

Now that I think of it, I should wash it today haha
