Our Thomas and Friends GoPak plastic bento lunch box is designed for kids, but can also be used by fun grown-ups who are really kids at heart. The GoPak has split compartments that allow parents to pack a sandwich or leftovers on one side and fruits, vegetables or other snacks on the opposite side. The interior lid keeps sandwich and snacks separate for packing lunches. This GoPak also fits perfectly inside most standard size insulated lunchboxes.
