The Metal Earth models are amazingly detailed etched models that are fun and satisfying to assemble. Each model starts out as 4 inch square metal sheets and you simply pop out the pieces using wire cutters or the Metal Earth Tool Kit and follow the included directions to assemble your model. No solder or glue required. You can take away my suits, you can take away my home, but there's one thing you can never take away from me: I am Iron Man.
