Moving on from the mystery of this polish, it is very lovely. It has great formulation to it, thin, but still very pigmented, making it almost a one coat wonder, which we love! I thought perhaps that there might be some issues with the consistency of these polishes because of their low price but I was delightfully wrong, and it paints on beautifully!
It's a lovely, almost pinky lilac shade, which is nice if you want a bit of pink on the nails without feeling like it's a little too "Barbie". Overall, excluding not knowing what it's actually called, I'd say this was a very good buy, especially when you consider that the RRP for a Nail Inc polish is around £11 per polish, and the individual polish price from the collection I bought, works out at around £3.60.
