This item is a posable, high-grade or better injection-plastic kit of an item from the Gundam universe.
Another of the designs from "Gundam Sentinel", an original Gundam story set in the same time period as Gundam ZZ, that was originally published as a serialized photo-novel in the modeling magazine Model Graphix.
Typical Bandai High Grade kit with beautiful detail and moving everything (except fingers). Standard snap-fit with poly-caps for joints. Parts are, as usual, pre-colored but painting will greatly enhance appearance.
