Cheeki Double Stacker bento box is a dual layer lunch box allowing you to keep food separate. The Double Stacker is like carrying around 2 lunch boxes. Unlike single layer bentos where the compartments are small, the Double Stacker gives two full size levels for storing larger food like wraps, sandwiches, sausage rolls, pies and all manner of things. Keep wet foods in one layer and foods that need to stay dry in the other.
