KIT
This kit of the flying saucer of the invaders was re-released in the 90's by Monogram.
It is in 1/72 scale and is molded in silver plastic, with transparent red parts. It's 7" in diameter (17.8 cm).
The kit is very good and has details of the interior of the ship and 4 crew members. Landing struts can be up or down. When finished, the top of it is removable which allows the sight of its interior.
