I have tested IsaDora's super slim eyeliner ”Flex Tip Eyeliner”And now thought of bidding on my review!
The tip of the pen works like a felt-tip pen and it is really, really easy to paint with! It is easy to get both super-thin lines and a little wider. Very easy to apply in other words. Often, long eyeliner tips are not able to absorb the eyeliner liquid only to the top, which results in the narrow tip being completely unnecessary - but it can do it! Hope it works just as well even when the eyeliner starts to run out.
I also like the color of the eyeliner, carbon black and opaque immediately when applied, neither too wet nor too dry and it dries quickly.
I think it holds up perfectly well, enough for my eyes. I did a durability test on my hand, and it holds up pretty well when you rub, but it is not 100% rub-proof.
The only thing I do not like is that it should be water resistant (it says at least on Eleven.se) but it really is not! Water resistant and waterproof are different things, but I can not even call this eyeliner water resistant and do not understand how IsaDora has performed that test.
IsaDora Flex Tip Eyeliner costs about SEK 109, and I can recommend it for people who like sharp eyeliners and want an easily applied product. But if you want an eyeliner that lasts for teary eyes, this is not for you.
I personally really like using this, and you will see it in many make-ups in the future :)
