Thanks, Ellaaa. I keep refreshing the Hermes tracking page but it's been "out for delivery to courier" since 05:32.
It's strange about the Bright Street Illuminator as you would think that as we got a NailKale base coat, the other NailKale product would be a top coat but all the descriptions of the illuminator imply it's a base coat as well. I don't recall any of the presentations mentioning using it as a top coat either, sorry.
On the Nails Inc site, it says "Bright Street Illuminator features iridescent pearls to brighten the pink nail bed and give the appearance of whiter tips and healthier nails" - so doesn't sound like something you put on top of colours.
On the QVC website, you can buy the same NailKale duo and on there it says: "Make sure your nails look fantastic even before you paint them with this nail treatment set".
