One eyeliner is enough

This is the Tony Moly Back Gel Eyeliner.

Since it is a model with an integrated brush, you don't need a separate brush, and it is convenient to carry around in a makeup pouch.

Since it is a brush shape, I found that it allows for more delicate expression when drawing eyeliner.

It also has good staying power, so it lasts all day during daily activities.

The price isn't expensive either, so I'm very satisfied with it in terms of value for money.
