This item is a fixed-pose, resin-cast kit of an item from the Gundam universe. It requires both cement and painting to complete or use.
This set includes crisply molded resin parts to build the backpack from Herbert von Kuspen's custom Gelgoog. Designed for use with Bandai's 1/144-scale HG MS-14S Gelgoog Char Custom or HG MS-14A Gelgoog/Gelgoog Cannon kits, these sharply detailed parts are molded in yellow (the photo below shows the parts cleaned up, painted, and assembled onto an HGUC kit; you'll need to do that yourself).
