I'm am super excited with my latest grab at the drugstore, especially since I've been on a glitter liner kick! I bought a couple from different brands recently but I have to say I'm loving NYX. They're super affordable and have a great range of colors, I bought a dark purple, a blue and a pink glitter. They all go on fab and have a great skinny liner brush. I also bought the black (which isn't featured on this post) that I'll definitely be using on upcoming video tutorials because it's so precise and opaque. Personally I think the quality and price makes these a superstar product. The purple and blue liners stayed on for quite some time where as the glitter was much more likely to peel off in a sheet... I've found that with the glitter liner if you do a thiner coat over another liner it tends to last longer.
If you don't have any--- I seriously recommend them!
