Reheat, steam, and cook with a glass microwave lid that doubles as a lid for a pot or pan. It’s safer, more durable, and longer lasting than plastic lids and wrap. Made of sturdy, non-porous borosilicate glass, it doesn’t hold on to odors, stains, or bacteria. It won’t break down when it’s heated up—and it can handle temps up to 450 degrees. Flip this vented topper over and use it to cover a pot or pan.
