Well, here is...an item.
It seems to be some kind of keychain (note beaded chain at the edge there) but why is it composed of 4 little semi transparent boxes with flip up lids? What are you supposed to do with it? And why give it a chain? If it was a pill case, nobody would need a chain on there. With the black/white theme, it's clearly from that "Welcome to the Next Level" campaign they had where they really pushed the slogan on all sorts of merchandise.

2 of the lids are blank, one has the slgoan, and the other is all black with a white line art Sonic face/pointing finger and the copyright. This is a slightly mysterious item.
