Primetime: Eliminates oil from the nail bed with the aim of making polish last longer. I didn’t find it to be that effective or worth the extra step anyway.
Bonder: A rubberised basecoat that is probably my favourite out of the trio – dries quickly and provides a smooth base for polish.
Polishield: A pretty decent top coat that makes my nails feel like silk and leaves polish shinier for longer.
Overall a pretty decent set for newbies to Orly, or those who have far too many polishes without enough nail care (i.e. me!).
