It's Nubar Reclaim. AND I LOVE IT!! I will go so far as to say it's my #1 (for now). It's a linear kelly-green holo that is just absolutely stunning! It has a gorgeous rainbow out in the sun. In the shade it's magic is hidden, but it's still a beautiful green. You can use a topcoat and it still works it's holo-y magic. I used 2 coats of Reclaim and topcoat for the pictures below.
You can get Reclaim on Amazon or the Nubar website. I highly recommend you get a bottle. You need it, period.
