These glass containers have clear plastic lids with a 100% airtight, leak-proof seal and secure latches to make reheating and storing easy. Built-in vents under the latches allow steam to escape so you can microwave food splatter-free, without removing the lid. Crystal-clear lids and bases make it easy to see whats stored inside.
