Colors: What you see is what you get. The color pay off is very true to what you see in the pencil. 936 Sky High is a bright medium blue with a satin finish. 937 Teal is a forest green with gold shimmer.
Formula: The liner was very smooth and creamy to apply. However, you do have to be careful of creasing as it is so creamy. The color is extremely pigmented, and you do not need to tug at the skin at all. I wore the 937 Teal color and unfortunately found transfers of the gold shimmer around my eye area. I remember 936 Sky High wearing very nicely but I think the addition of shimmer makes it more difficult to stay put.
Overall, the NYC Waterproof Eyeliners would be good if you are on a budget and wanted to create a new look. Especially if you only need to photograph or wear it for a few hours, the color and pigmentation is great! The longevity isn’t quite what I hoped for and is mostly gone by the end of the day. Shades without the addition of shimmer would fare better.
