The summer months can be hard on our chocolate covered pecans during travel so we offer temperature control boxes to help keep the chocolate covered pecans from melting. The dimensions for the inside of the medium box are 8x6x9, the large box is 12x10x9. The medium box may hold up to 5 16oz bags or the 16oz tray/tin. The large box is the only box which can hold the larger trays of 32/36 oz's.
