Quality is great and packaging is grat. YSL polishes are best with Shiseido. I did not like this color because I wanted it to be more opague and less metallic. It flashes pink which I also dont like. It looks like sheer silver on me and not very blue at all.
I don't wear much nailpolish, so when I do buy it, it has to be special. This definitely qualifies. Bleu Lune or "Blue Moon" is one of the Summer 2004 colors, and its an ethereal pearlescent soft blue in the bottle, but goes on as a softly shimmering very pale pink/purple. Is a very subtle polish, but so much more beautiful than most. The bottle itself is also elegant, a tall slim rectangle with the signature gold cap. Cost with tax I think was around $18, alot for a nailcolor but a price I was willing to pay for exquisite packaging and a color I'd never seen anywhere else!
