This is a posable, Real-Grade injection-plastic kit of an item from the Gundam universe.
The second release in Bandai's new "Real Grade" series is Char's Zaku II! Just like the first kit in the Real Grade line, the RX-78-2 (linked below), the Zaku II packs an amazing level of detail (think MG or PG) into an HG-size kit, complete with dynamic action and moving features. The perfect counterpart to the RG Gundam, the Zaku II comes with the same kind of posable inner frame, piping, and enough markings to keep you busy for some time. Bandai continues to raise the bar. Now, which Gundam will be RG#3?
