I recommend this eyeliner.

Since it's summer, I'm using a smudge-proof Kiss Me mascara.

It was so good because it didn't smudge even when swimming. So, the eyeliner too

I bought the Kiss Me eyeliner in brown. It's a brush pen, and as expected, it doesn't smudge, which is great😊

However, since it doesn't come off easily, a remover specifically for children is essential.
