MAC Glitter Eye Liner
- Comes in a clear tube with a thin liner brush. The bristle is very soft. The consistency is just about right, not too thick and not too light. The glitters are tiny, as described by MAC they are "micro-fine glitter." It stayed on pretty well and comes off easily with water/cleanser.
Urban Decay Heavy Metal Eye Liner
- It also comes in a clear tube with a thin brush so you can see how much there's left of the glitters. The clear liquid gel that holds the glitters together is quite thick. It comes off a little bit more messy than MAC. I have to use eye makeup removal to remove all traces.
Overall, MAC is more suitable for every day look if you're looking for a little sparkle to your eyes but not too dramatic. UD is more vibrant and intense in colors but a little too much if you're going to wear it for a day look. The only downside to MAC is they mostly come in limited edition, whereas, you could get UD anytime at Sephora.
