This is quite tasty chocolate delivered in a gold foil box. Each piece is nicely decorated so the overall effect is very attractive.
Just know that the chocolate is not particularly creamy or buttery. In other words, you are getting hard liquor rather than a fine wine. To me, a heavy chocolate means a darker flavor with not so much sugar in it. If you enjoy that, you will love these chocolates.
The best way to eat them is to let them warm up. Then you will get their full flavor.
