Fillimilli Blending Brush

My eyelids have been drooping so much lately, and since I've been going out without makeup, I figured I couldn't go on like this, so I bought a brush and an eyeshadow to try out. Olive Young recommended the FilliMilli brush, so I bought it and have been using it.

I haven't used many products like this, so I can't really say if it's good or bad, but it applies well.
