This is the best eyeliner. It beats any other drugstore or department store brand I have tried. I love how easy this is so use. I use it everyday and one pen lasts around a year. This is a standby for sure.

I've purchased about 7 Revlon Liquid Eye pens in a row. I tried multiple eye liners, however, this has so far been the best as it's easy to draw lines, and it's the brush is the right thickness and hardness.

One of the few liquid liners I actually buy, easy to use, doesn't smudge much and doesn't fade that easily either.

The Revlon Colorstay Liquid Eye Pen works great for that nice, bold line on the top lid, and is amazing for the wing. It's got a nice, small point at the end for touch-ups and bends easy for flipping up a wing. Apply eyeshadow first, then the this liquid liner and it pulls the whole look together. I use the 'Blackest Black' color for a dark, bold line. This is my favorite eyeliner and I recommend it to everyone I can!

This is a pretty good drug store eye liner. Easy to apply and not messy like the brush like ones. I love how you have much more control but while achieving the same liquid liner look.

I think that this is a relatively standard eye pen. I haven't really found any eye pens that do better than this, but I have liquid liners that do a much better job. I really like that this is packaged in a felt tip pen format, as it helps the application process, and makes it pretty easy. That said, I do have liners that have a finer felt tip, and can give a more precise application. I also don't think that this should be in the color stay line, as it isn't very waterproof, and it does smudge a little. While it doesn't smudge as much as other eye pen type products, it smudges more than other liquid liners. I also appreciate that this doesn't stain my eyelids like other products, and that the color is a true coal black, but I do find myself having to go over the initial line to make the line more black.

Works very well! I buy it everytime

Love doing a winged cat eye as an every day look. I find that for precision, this pen style is the easiest to use in order to avoid crooked lines and mistakes due to a shaky hand. Though for about $10 it is difficult to get enough of the product at the tip to make the wing crisp looking. I find that when you go back to add pigment it will remove the previous line. Easy to use, but could be improved.

I was in search of a good eyeliner that doesn't smudge while I have a long shift at work. And I found it completely in Revlon's Colorstay line. My retro look I love stayed on all day without ruining the style I was going for like it usually does. The whole Colorstay line hasn't failed me yet!

This is a wonderful liquid liner for the price (and you can always find it on sale somewhere).
I wear contact lenses and have sensitive eyes and this is one of the only liquid liners that I have tried that I have not had a reaction to.
I wear the colour "Blackest Black", which is a true and pigmented black shade (as opposed to other black liquid liners that dry to a soft or muted shade) and does indeed wear all day (a full 8 hour day) for me .
As well, the pen makes the liner so simple to use (which is important to me in the early mornings when I am applying makeup while I am still half asleep!).
I would highly recommend this liner!
