Rubbermaid® Brilliance™ Glass Food Storage Containers are intelligently crafted, and beautifully designed. 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 what’s stored inside. The lids are made with StainShield™ plastic so they're stain and odor resistant, helping them stay looking like new. These food storage containers are space saving, with a modular design for perfect organization and stacking in your fridge or cabinet. The universal lids fit across all Rubbermaid® Brilliance™containers, regardless of material type. These Rubbermaid® containers are BPA-free, microwave-safe, dishwasher-safe, and freezer-safe. The glass container bases are also oven safe up to 450 degrees F.
