I like my hot food HOT and there's nothing worse than waiting for delivery pizza that arrives all squashed, gooey and cold (and on top of that, you're expected to tip the delivery person). CookTek has solved that problem! Their heated pizza delivery bags can hold up to three (3) pizzas and keep them hot at over 155 degrees for 45 minutes. The initial heating of the bag takes approximately 1 minute and the re-heating is only a few seconds. These bags have been available to the leading pizza businesses for nearly a decade and are widely in use due to their practicality and cost. Their ease of use is further enhanced by the fact that no cords are required.
