these are two clip&close food containers I bought on Saturday, with smaller containers inside (seldom available here in Italy...)
the one on the left for me is 670 ml but the two small containers are 250 + 250 > 500 ml (perfect for my diet! shoud fill one with vegetables and the other with rice/grains & legumes/fish/tofu )
the one on the right is for my boyfriend and hold 1100ml (!!!) but the three containers inside are 340ml + 150ml + 150 ml > 640 ml
the perfect lunch boxes to be taken on trips, as they are airtight and never let one drop of food out!
