I first got fluidline as i loved the look of liquid liner but just couldn't master the application of it on my deepset eyes and someone recommended this to me as the next best thing.
It took me a little while to master the application of this (but it was alot easier than liquid in my opinion) but once i got the right tool (the smashbox arched liner brush no21) there was no stopping me. This applied like a dream and dried very fast. The staying power on my lids which can be slightly oily is great and once it dries fully there is no transfer onto my creasline. I also use this on my waterline and it stays on very well indeed (after a few hours in a club dancing you many find a little clump of goo in the corner of your eye but nowhere near as bad as i've had happen with most liners)
The colour selection in these is not as good as it used to me but there is still a good choice and some of the colours and textures can be hit and miss so i'd advise if you can ttry them in the store first. Blacktrack and rich ground are great staples with great colour pay off and texture in my opinion. Shade if its still avaliable is a great forest green with great payoff but a slightly drier texture in my opionion.
You should definitly try these out if given the chance. The little pots last forever just be sure you screw the lid on tight or they will dry out.
