The waterproof liner contains reflective 3D beads, evenly applying itself with each opening of the cap itself. The idea for the new must-have eyeliner came from working with the smashbox professionals, who always need perfectly sharpened liners to be able to work on shootings quickly and accurately. 


For even more expression, surround your eyes first with a dark shade, then apply a lighter shade over them!

  • "Gorgeous colour ! Neptune is always in my purse ! I love this long lasting waterproof liner ! Works so well ! I've gone to the gym wearing this many of times and it's stayed on throughout ! I would defiantly buy this again!" in 83 reviews
  • "Application is so smooth. It's also soooo pigmented and doesn't smudge in my waterline. The eyeliner definitely does stay on for a long time.  It glides on so easily. I would definitely repurchase this item in the future. It's very easy to find at any sephora location." in 25 reviews

I use this product every day. I have tried every navy blue liner there is (practically) and this one is one of the best. Took me a minute to figure out how to advance the product out of the inside, but it is neat because it stays sharp. I will say I feel like it doesn't take long to go through one of these, but I use every day and line my upper and waterline (have forever and ever). I also will layer a thin line of black marker liner over it. Sometimes it does run a bit by the end of the day if its hot out. Love the color though and that it sharpens itself. Will continue to buy.

I had bought two of these eyeliners when they were on sale and I am very particular about my eyeliners because I have small eyes and my eyeliner tends to like fall and I end up with raccoon eyes even the waterproof the only type that I found that I've loved is Bare Minerals Smashbox and Urban Decay they never go anywhere I can always count on it looking just as good at night as it does in the morning when I put it on there smudge-proof bulletproof rainproof everything and with this particular brand you never have to use a sharpener so it's always

When I recently travel down to Florida this summer when it was really hot and humid I knew that I needed a liner that was going to look sharp be a perfect cat eye product and stay all day long even at Disney World throughout the park and throughout the water rides and this was it it stayed on from morning and it was great when I reapplied it and it was even better because it stayed all throughout the evenings as well best product

I feel like this liner does not show up. i usually wear eyeliner on my top waterline to give my eye lashes a fuller look without a top liner. I have to press very hard for the liner to show up. I do from time to time wear the liner under my bottom last and it just does not work for me when i want it to smudge out and look like a smokey look it does not work and when i wear it like a crisp line and i scratch my lid it smudges.

These are probably my favorite eyeliners Ever. Every time you screw the cap on it sharpens them so you never have to worry about having Adult point on your eyeliner. It's a really smooth crayon that does the lining so you don't have to worry about jabbing your eyeball with a pencil. These look great in every color. I highly recommend this gift pack from Sephora.

I absolutely love this eyeliner. It has a sharpener in the lid so it is always perfectly sharp so I can get right close to my lash line. Other liners I use sometimes are not dull enough to sharpen, but not sharp enough to make a thin line and I never have that problem with this one. I would definitely spend the money on this eyeliner.

Love love this product got it as a sample from ipsy and it is amazing. I have very oily skin and eyeliner usually runs on me even water proof ones. I tried this on a girls night out of dancing and when i got home and looked at my face this product still looked like when i put it on. Highly recommended

Buy this eyeliner if you like to rim your waterline and want the liner to stay put all day and all night! The color is intense and the staying power is on point! Super easy to use because it self sharpens so it's always ready to go! I always have the black and brown on hand and I'm loving Neptune!
