Todays polish is from a UK brand called Gallery Colours, they make cheap polishes that sell for around £1. I get mine from my local market and I think you can probably find them on ebay if you don't have anyone near you that sells them.
Lilac Shimmer was on it's own on the market stall, I think it was the last one left, so I'm not sure if it's been discountinued. It's a pale pinky lilac base with silver microglitter mixed in. It does tend to look warmer or cooler toned depending on the light and in real life the silver glitter shows up much more than it does in my photos. The microglitter gives the polish a textured look as the glitter looks like lots of little bumps and it can also look like a foil if the light catches it right, it's quite an interesting polish.
