This is, hands down, the best top coat I've tried so far. It dries withing seconds (hence the name) leaving your nails super shiny. I literally saw my reflect while looking at my nails, no joke:) I got it in a store where they sell supplies for hair and beauty salons, but you can get it at http://www.professionails.com/en-eu/catalog/11-nail-&-hand-care/1112-seco-seco-15-ml.
Looove it! I've always had problems drying my nails. It just takes so long to dry them without messing up but now after I'm done with my polish, I just slap this on and my nails are dry within the blink of an eye.
