One of the most sought after collections from China Glaze is the OMG Collection. I only have three polishes from that collection. I think in response to everyone wanting the collection to come back, China Glaze appeased us by giving us the Tronica Collection. It may not be as good as the original, but this color I really liked. It was opaque in two coats, but here three coats are shown. It may not be clear the holographic effects, it is rather subtle, but it is there and very pretty.
