Besides the US and Canadian packaging for single packs, a number of Star Trek Micro Machines were also released in Japan in boxes of this type, which was pretty common for small toys of all types in the country, as they often sat stacked on store shelves, instead of pegs.
The variety was confined to the "early" era of the Galoob line, so there weren't ships like the Defiant, Farragut, Sisko's sailing ship, etc, even though that would have been pretty amusing to see.
The singles packs that we got in the US and Canada are pretty much what the selection was with these Japanese-market single packs.
One cool thing about these is that they can be opened non-destructively and resealed, though in practice this probably didn't happen too often.
