5 Gum Black Edition
From what we can gather, this Wrigley 5 Gum Black Edition was a German release several years back. It's described as a "dark mystery of fruits", which according to the reviewer in the video below, is a pretty accurate description. The gum itself is grey but when you chew it, it becomes pretty black, so we'd say this product is worthy of it's "black edition" title and thus B.A.B. approved. We couldn't find any for purchase so pictures and video will have to do.
