In summer, it's the Clio eyeliner pencil that doesn't smudge even when you sweat, right?

It's the least smudging of all the products I've ever used.

It is a pencil type, but... I think it might be a bit hit or miss for some people.

I like natural-looking products, so out of all the ones I've bought, this one lasts the longest and is great. It removes makeup really well, too. Unlike some products that require a specific cleanser to take off, this one doesn't seem to. Anyway, I highly recommend it.
