We just got in a slew of the Metal Earth model kits. Each model kit come with 2 or 3 metal sheets that contain the pieces to make your model. Etchings on the metal gives detailing to your finished model. Simply detach the pieces and follow the instructions to create your own shiny metal models.
Putting the models together is moderately difficult and it really helps if you use needle nose pliers. Some models are more difficult than others. I personally think the tie fighter might be one of the more challenging kits. You need to bend the main body piece until it forms the round cockpit. Once formed it is very small and easily squished when trying to attach the wings.
Once built these are great additions to a desk or work space.
