I loved the full sized sample of this, so I bought the product. The first day I applied it, it came out dry and streaky. I figured maybe it just needs a couple of uses, but I was wrong. It's been 3 months, and this eyeliner has never ever been the thick, black eyeliner that I came to love from the sample. I used it everyday for 3 months, applying it first, and using the sample over it to fill in the gaps. I was too busy to go buy a new one, and I kept holding out hope that it'd magically work one day. What I total waste of money. Seriously, a $16 eyeliner that could have gone in the garbage on day 1. I'll stick to buying from Sephora and saving money on S&H at least.
