To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Its so hard to pick a polish from Amazon, as you can't truly see what color it will be on your nails. That said, when it arrived, it was garishly pink. I tried to return it, but it is NOT returnable! I don't see anything about not returning nail polish on the website, but perhaps I missed that it.
