Review (5/5): Works great!
Tried it as soon as it got here, very easy to apply. Even if you don't get a full inky stamp on the wing you still get a good enough stamp that you only have to touch it up a tiny bit with the other side. Made what used to be a 20 minute task into like a 5 minute experience tops. I would wholeheartedly recommend this product to anyone who wants winged liner on a regular basis!
