Trying to perfect the liquid liner??? I can tell you right now with eyekos skinny liquid liner you will catch on in no time!! It is in a pen form but it has a thicker brush than all the others I have come across. Eyekos brush is not as flimsy as the others which makes it easier to use.
It stays all day long as in it does not smudge at all and you need remover to get it off!!! This is by far one of the best liners I have ever come across. It is easy to make the “cat eye” look as you can simply press the side of the liner down on the outer corner (on an angle) of your eye and it makes it a thicker line and gives you the cat eye 
!!
I recommend everyone try this product !! You can purchase it at sephora stores! Also try their skinny black mascara it is also an amazing product it is a smaller skinner brush so you can get all of those little lashes on the inside corner of your eye.
