This product line was requested by members of the United States Personal Chefs Association. Richard Riggio of Riggio’s Personal Chefs, based in Tampa Florida, classically trained and certified, thought there was a need for distribution of small quantites of this Pactiv multi purpose product and so we added it to our line. He said to be sure and tell you that we carry “all the most popular sizes and that the product makes it easy for your customers to reheat product left behind or special orders”. Also, that you need only buy 1 single piece of any item. Each size has its own clear plastic dome lid. This aluminum container, black on the outside and gold washed on the inside, makes a chic package that will go from the refrigerator to the oven or microwave (not the lid) and makes a great presentation. If you have any questions, just email Robert at email@example.com.
