if you noticed, the boxes say "best of" on them. The originals for obvious reasons dont. So it will be pretty easy to distinguish which ones are original releases and whgich ones are best ofs. I had to do this when i was looking for an original wave 2 slimed peter and clear slimer pack. No one on ebay understood the whole "food in the belly thing". I looked on the database to see that the first wave version did not have the "TRU" sticker on it, while the re-issue did. Burt i digress, im pretty sure that my original ray/stay pack will be worth considerably more that the re-issue. /end on non-sensical rambling.
