The packaging is similar in all of them. The bricks are packaged in bags, there are instruction booklets and most include stickers too.
I was surprised with how many custom pieces there were in these kits. Given each of the kits is around 40 pieces, most had close to a dozen custom pieces.
These are the three kits all put together...
Each of the ships sits on a pedestal which has a light inside it. Squeezing the base lights the whole thing up, that's pretty cool. Of course, as expected the Klingon ship sits on a red pedestal whereas the rest of the ships have blue ones.
