BYS is an Australian cosmetic company that isn't sold in Germany. A while ago they released a Wonderland collection that contained 3 glitter polishes, "Down The Rabbit Hole" is one of them:
It's a black jelly base that contains large holo glitter. I took this picture with flash (which I normally don't like to do) so that the holo glitter shows up better.
You might think that this polish is pretty amazing, but let me tell you something: It reeks!
I'm not overly sensitive to the smell of polish & I've never come across a polish that doesn't smell, but this one?! *duh* It smells freaking awful of all the bad chemicals that it most likely contains (I don't think it's B3F).
Unfortunately I had to take it off shortly after I took this photo. I haven't heard that others have the same problem with the smell, so it might be only me, but the smell effected my love for this polish big time. So be warned!
