I looked them up, and found out that they are made by a company called Pernigotti.
According to Wikipedia, the chocolate mix is known as gianduja or gianduia, a sweet chocolate spread containing about 30% hazelnut paste invented in Turin (capital of Piedmont, Italy) during Napoléon's regency. In 1852 a chocolate manufacturer named Caffarel invented Gianduiotto. (wiki). The Gianduiotto is a Piedmontese chocolate whose shape is similar to an upturned boat (wiki).
In short- the Gianduiotto is a signature Piedmontese chocolate, shape and ingredients-wise.
The gold and navy wrapper both says Caffarel, which I guess is the chocolate manufacturer, on one side. And on the other, the gold says Gianduia, which according to Wiki is the hazelnut chocolate blend, and the navy says Gianduia fondente. According to Google translate, the second word means melting which I find quite true because the chocolates have a very airy consistency that allows the chocolate to literally melt faster than a normal chocolate would in your mouth.
The bottom of the golden wrapper says "l'autentico gianduiotto di Torino", which with the help of google translate comes out to roughly: the authentic Gianduiotto of Turin.
The navy wrapper says "antic ricetta" meaning old recipe.
I found the original/gold wrapper chocolate link online here. But I can't find the navy one. I'm pretty sure it isn't the sugar free version (light blue), so I'm guessing it's the classic/dark version because the chocolate is a little darker than the original milk recipe.
Definitely an European get-away wrapped into little chocolates.
