Application with this isn't perfect - it will drag and snag given half the chance, so if you're not a confident applier of nail polish, give yourself time for a few tries with this when you sit down to apply it. It's by no means horrible though, and well worth some dedication for the fantastic-looking and quite long-wearing results.
Being metallic, it is also not forgiving of smudging or dings during the drying stage, as these pictures show. However, it does have an application-friendly flat brush with a rounded end (not pictured, apologies), making it easy to splay out over the nail for a big smooth coat.
The polish costs under a fiver (I sadly can't find it on the website to check the price, but I believe I paid £2.99) and you get 9ml in the bottle. Grab this if you see it.
