As we read again and again that despite all the tests give plastics when heated unhealthy substances to the food, I have long wanted, until I found this box. It can warm up (of course, always cover previously removed and replaced by microwave cover as protection against splashes) excellent casseroles, pasta, etc. in the office in the microwave without fear of plasticizers etc. to have. And the lid closes bombproof, so you have to have no fear for his acts or laptop. The glass is very thick and sturdy.
