Review (4/5): I mean, it works!
I just got this in the mail today and was so excited to try it since I was in a rush.
The eyeliner STAMP is very light in my opinion. I was able to use it as an outline and go over with my regular liquid liner though and made it work. The regular side has a wonderful find tip but it gets wide so fast it's like using a giant marker!
It got the job done fast though which I really liked. It will take some practice to get perfectly matching wings, so be cautious!
