This product is kind of a bummer. The main issue is that the formula is super watery. The first application will look like water color paint…with lots of water.
The other problem is that the felt tip is so pointy and hard that when you try to add another layer of liner, you may move some of the first layer. You can see the gaps below where an attempt to add more liner scraped off the existing liner.
After the arduous task of applying this liner, I did not experience any smudging or smearing. So once it was on, it stayed on. If you’re willing to try it out, it is about $10 at drugstore.com. It definitely did not work out for me.
