Waterproof eyeliner

This is a brush pen eyeliner that I got to try because a friend gave it to me as a gift.

I usually find pencil types more comfortable, but this one was good too.

It is waterproof, so it is resistant to sweat and water.

So I think it would be good for summer makeup.

It's a brush pen type, so it's easy to draw with.

How about a waterproof brush-pen eyeliner like this this summer?
