I use GF10 Blanket. I always use liquid eyeliner, but because my eyes water (due to pollen, allergies, and age), no matter what I use, they always end up fading, so I apply a stick eyeshadow underneath and then apply liquid eyeliner. This makes a huge difference in how well the eyeliner lasts. Because I use it like this, I don't spread it all over my eyelid, and I feel like a thinner tip makes it easier to apply. I've used Opera's eye color pencil several times in the past. I like that one too, but it would often break towards the end, so I decided to try this one out. It applies smoothly and smoothly, with a good color payoff, but it also has a soft, smudged edge, so I love how easy it is to create a gradient look. The color lasts well, and it's not too sticky even without layering powder shadow on top. I think it's very convenient for quick makeup application, traveling, or for creating a casual, all-around look. I use this as a finishing touch after applying my favorite eyeshadow, and I don't find the thickness too noticeable, and it feels stable and comfortable to apply. Blanket is the darkest color in the lineup, but it's still a little too pale to use as a finishing touch. I'd be happy if they added more matte finishes and deeper color variations.
