This is a posable, older-type injection-plastic kit of an item from the Gundam universe.
The beloved mechanical mascot Haro appears in "Gundam Build Divers" as the Diver's avatar character, and now you can recreate it as a Gunpla kit in its variant orange color! It's palm-sized, fun to build, and features opening/closing ears, and replacement parts to display his arms and legs popped out. Bandai has even included parts to recreate its inner mechanical workings.
