These are not official playsets. They’re pieces of art, made by a fan, and are painstakingly-accurate recreations of some of Star Wars‘ most iconic movie sets, giving his action figures a „realistic“ place to stand.
Most are from the original Star Wars, though there are a few from TESB and ROTJ as well. They’re as perfect as they can be; they can even be adjusted slightly to either make them nicer for viewing, or adhere to the exact layout as seen in the films.
