The title tells all, a metal lunchbox that folds up like an encasing for a diagonally cut sandwich. When you open it up you get a glued-in plate made in elegant designs like replicate porcelain and fine china and more playful, colorful designs aimed at children. It may not be too eye-opening, but it certainly is an imaginative idea that brings back memories of elementary school superhero-laden lunchboxes, and it easily beats a brown paper bag. [smartemma]
