This is the strangest thing I've seen. The 18-pack contains 3 separate 6-pack boxes packed in one paper tray. One of the 6-pack I opened has only 5 cans inside!?!?! There is no sign of the box had been opened, sealed just like others. The other cans inside is somewhat little sticky. I can only guess a leaky can was removed during packaging but a new can wasn't put back?
Other than that, it's my favorite energy drink of all.
