Yo~
So like a previous post Overview of Past Mascaras, I have decided to make one featuring eyeliners :D
Here we have (from left to right) Revlon Colorstay Pencil Eyeliner (black), Hard Candy Stroke of Gorgeous (nautical - tealish blue), ELF liquid liner (coffee), Maybelline Line Stiletto (brownish black), Physician's Formula Eye Booster Eyeliner (ultra black), and Physician's Formula Eye Booster Felt-tip (deep brown)
Wow, that's quite a bit. I also want to add that these liners are due to be thrown away (way older than 6 months...) The swatches below are in the order I listed above. You can see that Revlon isn't that pigmented and the ELF one is pretty streaky (the brush applicator sucks) Oh and the PF Eyeliner can look brown in some lighting but it's very dark :)
