I bought a bottle of this through eBay on a whim recently, since the descriptions sounded like something I would enjoy--amber and glassy, aquatic notes.
In the bottle, my very first impression was that it was DEFINITELY glassy. It's sharp and crystalline and a little metallic; didn't initially seem like a very welcoming perfume scent.
Then I tried it on, and it was instant love. The amber showed up on me almost immediately and two hours later is still around. This is such a pretty, elegant scent. And to echo Czarina, it does remind me a little of No. 5, which isn't a bad thing at all in my case.
All in all, it's absolutely lovely and probably my new favorite BPAL oil. I always love the discontinued ones.
