Eek! These are so stinking cute! A smaller version of the Cabana Row House Mini Set... and there's even a platform they can all sit on (see link below; kinda like a boardwalk for a beach scene? Or a sidewalk, as I can see these as a block of snowy houses for a tiny Christmas scene, too).
The tallest of these is 3-3/4" tall. And that one is also shown below next to the same house from the original set so you can see the mini-ness.
Ship flat but laser-cut and pre-scored, so super easy to put together. A note from Teri Calia about folding such tiny houses: "Fold those scores really well before you start assembling; fold all the chipboard pieces flat at every scoremark before starting."
Set of 5 (with separate roof pieces, so 10 pieces in all).
