Sometimes wandering around the Internet aimlessly finds you some cool stuff, like these liqueur-filled foil bags.
These are novelty items that combine a small amount of flavored liqueur. I personally like the "Drinking Lizense". It unfolds to reveal a comical identification card authorizing you to take a drink.
The liqueur varies from product to product, but the one above is a blend of vodka-lemon-liqueur and vanilla-cream-liqueur.
German-based Rotstern GmbH & Co. KG. has a bunch of others like this. Take a look at them all.
