OPI often makes limited edition collections to tie in with movies and their most recent collaboration is with Oz The Great and Powerful. The collection contains 7 different shades I believe, but I got the mini collection containing 4 of the colours: I Theodora You a sheer pink, Don't Burst My Bubble a sheer white, Glints of Glinda a sheer beige and What Wizardry is This? a taupe and one of their liquid sand lacquers. The first 3 of the colours all have pastel hue and are very sheer, really pretty shades for more neutral looking nails. The last shades is the only one that packs a little punch. It is a liquid sand shade which means that it has a textured finish and you can see and feel the little "grains of sand".
I really like this little collection and even though the 3 light shades are a little hard to tell apart, I was looking for some sheer nail colours and I had wanted to try out one the liquid sand colours, so all in all this was the perfect deal for me, plus I really like the mini size bottles as I have yet to actually finish a with a nail varnish - of any brand :)

Oh and if you haven't seen the film yet, go see it, it's really good :)
