I have the packaging, but it's imported chocolate, and those labels usually don't feature percentages like I've seen on American ones. I've not tried the Italian limoncello (dark chocolate) one, but have had some of the German marzipan one (bittersweet chocolate) and yum! I usually get bittersweet and/or dark chocolate because I find them less cloying. I also had a bit of a British one, but it was too sweet.
I love dark chocolate for the reason it's not too sweet!
