The fact that this was a matte pencil is what drew me to it. It is a bright yellow that doesn't have any glitter to it. It's also definitely waterproof. Trying to rub it off after I swatched it in Sephora made me super excited to try it on my eye area.
It works great as an eyeshadow base. Just lay it down, even it out a bit with your finger and go to town with your eyeshadow and it's good to go all day without creasing or fading. I've enjoyed using it underneath champagne or light golden colors to bring out that yellow gold look.
At first, I didn't think this product stayed well on the waterline. But it seems to need a little bit of warming up at first, and then it did just great as a waterline eyeliner. It stays put pretty well too! After 3.5 hours, there is minimal change in the color intensity on my waterline and by the end of the day, you can still tell it's there, it's just lost a lot of intensity and transferred along the lashes more than right on the waterline.
Overall, I'm glad I picked this one up! It's unique and works well!
