I’ve been seeing these for some time and think that they’re pretty cool. Basically they’re small cardboard models of spaceships that you make yourself. I’m not sure, but i think that there’s some sort of game involved too. I still need to get both of these. I have seen them about, but have found the cost of postage and packing to the UK to be pretty prohibitive. 😦
They’re available as both the Millennium Falcon and the Steller Envoy which is pretty cool.
