Price: I paid 1,99$ at cherry culture (the shipping was a bit high because of the wheight of the polishes)
Packaging: Your typical glass nail polish bottle, nothing special. But it seems quite sturdy and the cap screws on tightly so the polish does not dry out.
The black (ish) based polish is filled with fine silver/holo glitter and big holographic hexagons. I love how this sparkles!
The polish is not opaque, so I use a dark nail polish underneath it to make it look more even.
My picture does not do this polish justice, but it was the best I could do.
I can't really say much about how long this polish will last on your nails as I always remove it after a few days, my nailpolish always start to chip after about 2-3 days.
I will definately try some more NYX polishes out in the future.
