Nicki Minaj for OPI

Hello lovelies i hope your all well. So its safe to say that i have a MASSIVE obsession with nail polish, so much so that im trying my utmost to stop myself from purchasing anymore (i have a big box of polishes and still tell myself i dont have a colour to use :S)..So when i heared that the Nicki Minaj collection had been released, i tried to ignore all temptation, such as beautybay and reading reviews, but i didn't think my biggest temptation would be at the hairdressers..in the month or so that i haven't been they have introduced Moroccan oil and OPI to their new brands (so you can understand any strength went out the window) aswell as my beautiful hairdresser declaring how lovely and in season the colours were, so i left the salon with new hair, new polishes and £12 shorter than i originally expected :S.. anyway enough of my rambling and onto the colours.

Im not exactly a fan of Nicki Minaj so the names of the polishes mean nothing to me.. but the little set comes in:

 Did it on em-an almost lime, perhaps yellowy green, which does not seem to unsimilar to OPI's who the Shrek are you?..however i dont own this polish to compare, anyone who does, id love to know whether its a dupe or not!!

Fly- A lovely teal colour, im a total fan of this colour on my nails, so i think this will definitely be getting alot of wear out of this 

Pink Friday- a lovely light creamy pink colour (im really loving the pastel theme going on)

Metallic 4 life- tbh im not to fussed on this polish, its basically silver glitter within a black base, my opinions could completely change when i get around to using it!!

Altogether- im really impressed with this collection, although i would have preferred Save me (a blue holographic glitter) than metallic 4 life, but that's just personal choice. The colours are lovely (im a definite fan of Fly and Pink Friday), however the shades are not to dissimilar to others out there. 

Price- £12ish for the set which is pretty good when a single OPI polish is usually about £10 

Quality-like all OPI Polishes, you need about two coats for an Opaque look

So have you tried anything from the Nicki Minaj Collection? Any similar dupes?
