This is the "Sonic & Sega All Stars Racing Transformed Lunch Kit". It consists of a soft sides insulated lunch box carrier & a metal thermos with plastic rounded top. As you can see, it has the 'transformed' vehicles in the same CG design for both items, on a blue 'sky' background. The edge & handle for the box are red, as is the thermos cap. It is likely the same company produced all of these items. However, it is not confrimed if this was ever actually released. It's not a prototype because clearly, the product is real in the photo. Also, it was at the Mercedes Benz event as some type of prize or possibly kiosk sale item. However, it was so limited, there's no confirmation.
