@Solemn_In_Berlin: thanks. yep, I like all the stuff in the packages, so I open them. although the collector's value decreases, I don't want to sell it anyways...
@themidlandmaster: I bought them here:
http://shop.nukacola.eu - they come on bottles with a tasty nuca cola inside, those are not just bottlecaps.
btw you can see the top of some bottles on the bottom of the first picture. the "quantum" is "blacklight active", now I need to install some UV-LEDs in the cupboard.
