Ziruma Glass Food Storage Containers 35 oz — 4-Pack Gray Airtight, Oven & Freezer Safe

Ziruma 35 oz non-toxic glass food containers with airtight gray lids are a 4-pack of plastic-free storage designed to keep meals fresh, leak-free, and safe for everyday use.

These containers pair 100% borosilicate glass bodies with matching glass lids that eliminate plastic contact with food while offering oven-, microwave-, freezer-, and dishwasher-safe convenience. Each 35 oz (about 4.4 cups) container suits meal prep, leftovers, and transport—helping you portion, store, and reheat without swapping dishes or exposing food to unwanted chemicals.

How do these containers prevent plastic from touching my food?

The Ziruma set uses borosilicate glass for both the container and the lid, providing a fully glass-to-food contact surface. That means no BPA, no phthalates, and no hidden plastics leaching into your meals.

• 100% borosilicate glass construction, lids included
• Plastic-free seals where food contacts the surface
• Clear glass for visible contents without opening

Are they truly airtight and leakproof for transport?

These containers feature a snug sealing design that reduces air infiltration and helps lock in flavors and aromas. The leak-resistant fit lets you carry soups, stews, and sauced dishes with minimal worry about spills when properly closed.

• Tight-fitting glass lids to minimize air exchange
• Stable, stackable profile for suitcase or fridge organization
• Suitable for lunch bags and short-distance travel when sealed

Can I freeze, heat, and wash them without damage?

Ziruma containers are built to handle temperature transitions: freeze your meals, reheat in the microwave or oven, and then clean them in the dishwasher. Using borosilicate glass reduces thermal shock compared with ordinary glass, but standard care—avoiding sudden extreme temperature shifts—extends longevity.

• Freezer-safe for long-term meal storage
• Microwave- and oven-safe for reheating and serving
• Dishwasher-safe for effortless cleanup

What size and meal uses work best for these 35 oz containers?

At roughly 4.4 cups, each container fits single large meals, family-style sides, or bulk-prepped portions. They excel at weekly meal prep, portion control, storing leftovers, and keeping an organized fridge without using disposable packaging.

• 35 oz capacity ideal for dinner portions or multiple servings
• Clear glass makes content and portion checks easy
• Stackable 4-pack conserves fridge space and simplifies rotation

Who this is for: Choose Ziruma if you prioritize chemical-free food storage, often prepare meals ahead, or want containers that move from freezer to table without extra dishes. This 4-pack suits busy households, meal-preppers, small families, or anyone shifting away from single-use plastics toward cleaner, durable kitchenware.
