The Urban Decay 24/7 Glide-On Waterproof Eyeliner Pencil is pretty well-known for sticking around all day, especially the Perversion shade, which is a really bold matte black. According to what the manufacturer says, it's waterproof and smudge-proof, and they claim it can last up to 16 hours. Plus, it has some hydrating stuff like Vitamin E and Jojoba Oil, which helps it go on smoothly.
A lot of folks have mentioned that this eyeliner really does last a long time and goes on easily without pulling on your skin. From what we've gathered, many people like how it holds up throughout the day, even when conditions might usually make makeup smudge. It's also a hit with people who have sensitive eyes, since it doesn’t seem to irritate when used on the waterline.
That said, a few people have mentioned having a hard time sharpening it. The wooden casing can make things tricky if you don't have the right sharpener, which sometimes leads to wasting some product and getting an uneven tip. A trick some people recommend is putting the pencil in the freezer for a bit before sharpening to get a cleaner edge.
Though it's supposed to be waterproof, there are a few mentions of slight smudging under really tough conditions. Still, folks seem to love its rich colors and the fact that it's cruelty-free.
If sharpening becomes a hassle, you might want to think about mechanical eyeliners that don’t need it. One alternative people seem to like is the L'Oréal Infallible Never Fail Eyeliner, which is easier to apply and has good staying power for a lower price.
