For most makeup products, I believe that good quality items exist in the drugstore, but I have yet to find a really excellent eye liner (not in liquid form). I didn't really realize how nice liner formulations could be until I tried a few higher end ones, and I am still looking for the more affordable dupe. Would it be from Palladio? For $3 per liner, that'd be a good deal.
Here are the 3 that I'd picked up.
The biggest downside I saw, at first, was that they weren't retractable. I like those types simply because I am lazy and like not having to sharpen them. However, if they turned out to be good quality, I could deal.
Pass on these.
