The best liner I have ever used, hands down. They outlast everything, they have the ease of use of a texta (sharpie) pen, the have a good colour range, and they glide on so easily.
There is nothing to not to love about these except how difficult they are to find and buy.
The heads are double sided, and if you make a mistake they even have a little clean up pen you can use as well.
They outdo ever single eye liner I've ever used.
this is the waterproof line of eye and lipliners that Kryolan has. And let me tell you....they are truly waterproof and amazingly longwearing-wont come off even when rubbing!!! the package reminds me that of a permanent marker with a fine tip - and the genius part is that you can acctually get the tip off, flip it around and stuck it in again so you get a brand new tip if the one side get worn off (dual sided tip). these skinliners can be used both as eye and lip liners, and there is always the clear corrective pen (skinliner corrector) to correct spots you may accidentally smudge or for a more defined lipline!
