I am reviewing eyeliner.

This is the Cash Cat Easy Eyeliner.

I bought this quite a while ago, but since I use it only once in a while, I'm still using it. It's a brush-pen eyeliner.

The advantage is that even a beginner like me can draw well with it. However, for someone like me with deep double eyelids, the downside is that it smudges easily. It also seems like they don't sell it much these days. Still, it's decent enough.
