As I mentioned a few weeks ago, I am completely obsessed with EYEKO's liquid liner:
the line it gives is perfect and because the pen is made to keep the felt tip very hydrated (aka: soaked with the liquid liner pigment) you hardly have to put any effort in to getting a great line!
I've been wearing the Olive Green shade on weekends in the form of a super thick cat eye
at $15 (Sephora and Birchbox) you can stock up, because they last forever! Its worth paying for this product because the tip never goes dry, even if you have a lot of eyeshadow on.
Its a MUST have in my beauty bag!
