My experience with Revlon ColorStay one-stroke defining eyeliner:
The eye pencil is super soft and creamy.
Very easy to apply on top or bottom of eyes without any tugging or pulling.
Color pay off is excellent, just one stroke is more than enough for the perfect black line on eyes.
Water-proof and Smudge-proof-TRIED and TESTED. Once it s set(which takes approximately 20 secs)we are free of any tensions of bleeding or smudging.
Very long lasting-stays put whole day long, in fact until I remove it off. Color does not fade away too.
Gets removed quite easily with olive oil.
