This material has an extremely low coefficient of thermal expansion, ensuring exceptional thermal shock resistance. It can safely withstand the drastic temperature change from being taken directly from the refrigerator (or even freezer) to a microwave or oven, completely eliminating the risk of breakage and providing users with a worry-free experience.

Whether carrying lunch or storing pre-prepared meals in the fridge, it locks in freshness and flavor.
