It's the hot food equivalent of the J19 Salad on the Go comes with integrated knife and fork.  Perfect for hot lunches at work or college.

Now in neon green with bright blue accessories.

See the product in action in this French demo video.  Note how all the kitchens are Tupperware-equipped!  Also, there is some curious morality at play in the film:  the first woman steals her colleague's Tupperware from the office dishwasher (which is unforgivable), then her daughter allows her boyfriend to think she cooked the meal herself.  The French, eh?

Use it at max 600W for reheating, not at full power.  The food's already cooked, you don't need to cook it again.
