We pack our frozen products in a cooler within a shipping box with enough dry ice to keep the contents frozen well into the evening of the delivery date. A cardboard insert is placed on top of the product, before dry ice is added, as a barrier. It is best to open the package immediately upon arrival and put your desserts in the freezer, until you are ready to enjoy them. Use gloves when handling dry ice. Fun Fact: the temperature inside that box is about negative 110 degrees F which is colder than your freezer by 100 degrees.
