The less than desirable thing about OPI polishes is that they are a little hard to find. If you know of a local salon that sells the polishes then you are in luck; if not you might be searching for a little bit. Luckily there is a great OPI vendor locator on their site (you can access it here)
One other thing that I wish was different about hte OPI polishes is that they have an "extra wide brush" Which I think is something they pride themselves on but I think it makes it a little tricky to paint your nails with.
But other than that I absolutely recommend OPI nail lacquers. Whether it is the gorgeous colors, their quirky names or the great price ($8-which may seem like a lot but the lacquer is a very high quality), you can't go wrong!
