I bought the Nicki Minaj collection minus the shatter on eBay as OPIs are really expensive over here in Australia - $20 per bottle- so I buy them online. I wanted to do a mani using one or more of my new polishes because I was so excited, I don't even think the collection is out here in stores in Perth yet.
Here is a half moon mani using Opis Pink Friday and Did it on Em. It was my first time doing a half moon mani, and I looked up how to do them properly and people on youtube were using the file reinforces as guides for the bottom. I didn't have any of these so I used french tip guides which were really fiddly. I gave up and did the rest free hand.
Here is a close up picture so you can see the half moon closer.
I hope you like it!
