Review (3/5): It's ok...
For $4.99 it's decent. The wing stamp works well & the black liner looks nice but it smudges very easily & after having it for about a month I left it in my makeup cup wing side up for a few days & the stamp completely dried out. I turned it to see if the ink would go back to the wing but it's still dry. If you have oily skin at all, I wouldn't recommend it.
