I feel that this paper which I found online, is really good for wrapping chocolate. It is golden and tissue-like, with small circular imperfect perforations. These perforations allow you to see inside the wrap. This is a peanut butter and milk chocolate filled candy bar.
I know some may be turned off by the fact that the chocolate is exposed, but I feel that it is a very good way to show the chocolate without exposing it completely.
