Years and years and years (we're talking probably around 5 years or even older), apparently i got one of these from a gift with purchase in Intense Ivy shade. I put it in a drawer somewhere and promptly forgot about it.
Queue 2019, i've stopped buying more stuff when i know i have so much in my drawers, so as part of that process of downsizing and figuring out what i can use, what i need to use up, etc., i went through all of my liners. In the process of swatching all my liners (including colored stuff), I discovered the gwp quickliner from yeaaaaaaaaaars ago.
First, i'm honestly shocked that 5-8 years later, it's still creamy and doesn't budge. What even, it's crazy. And it haven't gone bad or anything because it haven't been irritating my eyes, and in fact it stays put longer than many of my other more expensive and fresher liners.
The color name is apt, as it's a dark shimmery green - it's basically a black that pulls a yellow-green, so can certainly be used in lieu of a standard black. It is creamy and smooth, goes on my lid so easily with no tugging or harshness, but dries down quickly and then it doesn't budge. i never have trouble with this liner smudging at the inner corner - or rather my inner corner folds kind of funny, and so most liners ends up smudging there and then i got some black stuff on the bottom side of my inner corner. This liner DOES rub off at my inner corner, however it somehow rubs off clean (i have no idea how), because it doesn't make the bottom of my lashline grimy and smudged.
I am seriously enjoying using this product. It IS a bit expensive though, so i'm not sure about repurchasing when i have so much other stuff, but it's definitely on my "maybe" list for repurchasing when i'm done with all my liners, it's that good. I also like that it's a retractable pencil which means no need to sharpen, and it's not so thin that the tip breaks (which i've experienced with some japanese retractable liners). I DO know that there have been instances with other brands where the black smudges but the brown or the shimmery shades don't, so there IS a chance that the cream black version of this might smudge, but I'll figure that out when i get to it.
This reminds me of my favorite drugstore retractable pencil liner (Physician's Formula's shimmer strip retractrable liner trio in brown eyes), but twice as good (but also twice as expensive!)
