This item is a posable, Master-Grade injection-plastic kit of an item from the Gundam universe.
This particular version of the Rick-Dom never appears in any Gundam TV, only in the original novel as written by Gundam creator Tomino. Collectors love this stuff! Different color from the standard release, new weapons (Zaku Machinegun), and also includes an unpainted 1/20 Char figure, in military costume.
