not to leak, Rubbermaid Brilliance Meal Prep divided containers are intelligently crafted and beautifully designed. These premium StainShield plastic containers have crystal-clear lids and bases so it's easy to see what’s inside, plus they're stain- and odor-resistant, helping them stay looking like new. The leakproof lids are built with an airtight seal and secure latches. The 2 compartments make prepping a full entree and side dish easy, while the splatter- lid design with built-in vents under the latches allows steam to escape so you can microwave food with the lid on. These food storage containers are space saving, with a modular design for kitchen organization and easy stacking in your fridge or lunch bag. Plus, the Smart Lid System allows you to share your lid across all same-sized Brilliance containers, regardless of material type. These Rubbermaid containers are BPA-, microwave-safe, dishwasher-safe, and zer-safe.
