From the release:
Bring a touch of the old world to your city with the Ryokan. This could be a retro hotel, the headquarters of a Yakuza clan or maybe the entrance to the "flower and willow" world.
Once constructed it can be stored by stacking the components inside one another to save space. The roofs are removable to allow models to move inside. It can also be used as two separate buildings.
It is made from 1mm heavy card and comes supplied unassembled and unpainted in an A4 flat pack.
It costs $19.50 and worldwide postage is only $4.65
