The Front
Make sure the right font has been used and that it is aligned properly, without being skewed.
The Back
The address of the distribution centre in The Netherlands and the address of OPI in the US. should be on the back of the bottle. Also there are 4 warning signs that always come in the same order (as seen in the pictures) And if you dont see all 4 of the warning signs then you know that you have a fake OPI polish.
The Label
A genuine OPI bottle always has a double label on the bottom of the bottle. The first label has information such as the product name, product code, bar code and the 'Peel Here' suggestion. On the back of this first label you will find the ingredients. The Second label has the product name and code aligned in the center, and no barcode.
Serial Number
Genuine OPI bottle have a serial number engraved, on the side, towards the cap. You can't really see them that well, but they should be there. Now if the serial number is extremely noticable, then you have a fake OPI polish.
Balls
OPI bottles always have two steel balls in the bottle. If there's more or less then you have a fake polish.








This got me thinking... the last time I went to get my nails filled in, I took a look at the OPI polishes because they had a BEAUTIFUL collection. I didn't see some of the things that are on your real OPI. Hmmm, this will make me want to inspect them the next time I go to the nail shop.
