This is an injection-plastic kit of a science-fiction/anime item.
From Good Smile Company:
From the anime series "Magic Knight Rayearth" comes a MODEROID plastic model of Rayearth, the Spirit of Fire! The mecha's appearance from the anime has been carefully preserved with detailed sculpting, and certain areas of the model have been recreated with translucent parts. The flame effects on its back recreated with translucent parts are removable.
The model also comes with interchangeable hand parts, its sword and its shield. It is primarily made of PS&ABS, and features colored runners and pre-colored parts, making it easy to recreate the mecha from the series with a simple assembly. Be sure to add the MODEROID plastic models of Ceres, the Spirit of Water, and Windom, the Spirit of Air, to your collection as well!
