Please recommend an eyeliner~

I use eyeliner almost every day, but since it dries out or smudges quickly, I have to switch products often, so finding a cost-effective eyeliner is a big concern for me.

In particular, I prefer thin lines that define the eyes rather than thick ones, so I like liquid products that draw a slender line.

However, some brushes were too thick so the lines smudged, and others dried too quickly so the lines didn't come out smooth.

If you are looking for a cost-effective eyeliner like me that applies thinly and cleanly because it is a liquid type Are there any recommended items that meet these conditions: a product that doesn't smudge easily, has good staying power, and is easy to wash off?
