MAC Cosmetics Prep + Prime Primer 12 ml

By far the best eye primer I've had. For me, no more others. Even very cheap eye shadow stays super good with this primer. You can apply it with your fingers. Let dry for a while. And then apply your eyeshadow. It's a bit more rough because of the primer, but that's what I like to do for it.

Really a great product. Eyeshadow is still perfect after a whole day. Even with teardrop eyes of the hay fever, nothing really works out.
