The medium platters are the perfect size for carrying my baked goods in a cool box to the monthly farmers market i attend. Not only are they handy for transporting my pastries, they also can be used to protect from coughs and sneezes whilst on display. Having clear lids the goods can easily be seen . They neatly stack on top of each other so no more struggling with trying to protect goods from damage whilst moving the cool box from car to venue. All in all, perfect for my needs.
