From freezing batches of marinara or popping prepped veggies in the fridge for easy weeknight dinners, these convenient leak-proof containers are perfect for anywhere your ingredients need to stay fresh and organized. The lightweight, durable design makes them great for picnics and parties, and the containers conveniently stack and same-shape items nest together when not in use for fast, smart storage that won't clutter up the cabinet. Leak-proof, 4-hinge locking lids feature an enhanced silicone seal that's airtight to keep foods fresh longer and prevent accidental spills and drips. Plus, you can heat and reheat meals and leftovers in these made-to-last containers that are microwave safe for convenience (lids should not be locked during microwave use) and dishwasher safe for easy cleanup. Keep your food prep and storage smart, simple, and stylish and save more cabinet and pantry space with the 30-piece Leak-Proof Stacking Food Storage Container Set.
