Secret Key Twinkle Waterproof Gel Pencil Liner Warm Bronze

I really like this liner. It doesn't smudge easily, and there are so many shades. The ones with shimmer are great to use like eyeshadow, and the price is incredibly affordable. It's a sharpenable type, and thanks to its waterproof and oil-proof features, it doesn't smudge for a long time. It applies smoothly without feeling stiff, but it does get a bit dry if left on for too long. However, once you sharpen it, it works like new again.

There are many colors, but this one suits warm undertones exceptionally well. It has a brown tint, but feels like a slightly dark cherry type, giving it a red-brown vibe. It is easy and convenient to apply with just a few swipes, so I often use it instead of eyeshadow.
