This Snapware 18-piece food storage set features stain-resistant Pyrex tempered glass containers with BPA-free lids. The set includes nine containers in various sizes: two 1-cup round containers, two 2-cup rectangular containers, two 4-cup square containers, two 4-cup round containers, and one 6-cup large rectangular container.

Each container comes with an airtight, leak-proof lid featuring four locking tabs for secure closure. The lids include a convenient write-and-erase surface for labeling contents. The tempered glass containers are microwave, oven (up to 450°F without lids), refrigerator, freezer, and dishwasher safe. The space-saving nesting design allows for efficient cabinet storage.

For best results, thoroughly dry the lids after washing to prevent mold growth around the gasket.
