My personal review of a lip liner I would 100% repurchase

The Banila Co lip liner is seriously a gem! It glides on so smoothly that I wondered if defining the lip line had ever been this easy. If you lightly smudge it with the brush on the back, you can achieve a perfectly natural-looking over-lip. The staying power is also great, so the lip line stays sharp even after eating. Even those with clumsy hands will see a dramatic change in their lip look with just this one product!

It's currently on sale at the official Naver store as well, so I highly recommend buying it. :)
