Hi everybody. Hope you can help me out here. I'm about to buy this set from a private seller - the box has been opened, but all bags are still sealed. So that's all fine... My concern is that I would like to be quite sure that ALL bags are there. So... Can any of you guys inform me how many bags this set is holding - I tried to look on some pictures on the mighty internet, and counted 24 bags - but is that right? Thanks a lot for any help... /Autechre
