I recommend Daiso brushes.

It is best to wash products like brushes frequently, but since I can't do that, I tend to replace them often. If I buy them at places like Olive Young, it is too expensive to handle.

I don't think it will work, but since Daiso is only 1,000 won, I stock up on a few at a time and use them. That said, compared to branded products...

There isn't much difference, so I am using it well.
