essence liquid ink eyeliner waterproof, eye liner, no. 01, black, defining, long-lasting, waterproof, vegan, perfume free (3 ml)

I've been buying this for years. Love it. Brush is easy to use, and gives a super 'thick-to-thin' gradient if you want it. Also allows for lovely little wing flick at the edge of the eye. Also easy to paint swirls or symbols at the corner of the eye. Stay on all day. No smudge

It really is waterproof. Really good product, stays there. Only waterproof remover can take it off.

Best waterproof eyeliner, easy to apply and stays on when swimming or in the rain

I like this product and have been using it recently. My biggest annoyance is it is a tiny product which won't last long. Probably good to take on holiday if you are being careful what you pack. Probably would only purchase for holidays in future.

I have worn liquid eyeliner for 12 years and tried a range of high end and drug store brands. My holy grail was the Nyx matte liner until it was discontinued last year. This liner is a complete replica. Its the perfect consistency, truly waterproof and an opaque matte black shade. The brush is perfect for extremely precise, clean application and I can get perfect wings done in about 2 minutes despite having shaky hands. Doesn't drag on the skin (even after powder/ eyeshadow) and you don't end up with overdrawn, large ugly wings trying to correct your mistake (which happens with most eyeliners). I'm recommending this to every make up wearer I know.

Good quality eyeliner, very black, lasts ages

I go through so much eyeliner it's not even funny, and having tried a bunch of different brands in my time I can safely say that this is my favourite! It lasts all day and the application brush is so easy to use, I'd recommend to anyone!

Doesn't last smudges
