Ziruma Glass Food Storage Containers, 4-Pack Multi-Size Beige — Borosilicate, Airtight & Non-Toxic

These multi-size borosilicate glass containers come in a coordinated beige finish and include four capacities for everyday use. Each piece — lids included — is made from 100% glass to eliminate plastic contact with food. The set is crafted for durability: it resists thermal shock, works in the oven, microwave, and freezer, and cleans easily in the dishwasher.

How do Ziruma glass containers keep food fresh without plastic?

The full-glass construction prevents plastic chemicals from touching food, and the lids form a tight, leak-resistant seal that helps retain flavors and slow exposure to air. Because both base and lid are borosilicate glass, there’s no plastic lining to absorb odors or stains.

• 100% borosilicate glass bases and lids for a pure storage surface
• Airtight seal prevents spills and reduces air exposure
• No BPA, no phthalates, no plastic contact with food
• Neutral beige finish that resists visible staining

Can I freeze, reheat, and bake with these containers?

Yes — the borosilicate composition tolerates wide temperature ranges, so you can move meals from freezer to oven or microwave. Always allow for gradual temperature changes and check manufacturer guidance for maximum oven temperatures.

• Freezer-safe for long-term storage of meals and leftovers
• Microwave safe for reheating (remove lid if needed to vent)
• Oven-safe for baking or warming (refer to max temperature limits)
• Handles thermal transitions better than common soda-lime glass

Are these containers suitable for meal prep and on-the-go lunches?

The 35 oz (4.4 cup) size in the pack is ideal for full portions or batch-cooked meals, and the leakproof lids let you carry soups and sauces without worry. Their stackable shapes save fridge space and make portioning simple during weekly meal prep.

• Multiple sizes accommodate single meals, sides, and snacks
• Leakproof lids allow safe transport in bags and lunchboxes
• Stackable design keeps fridge and pantry organized
• Durable glass resists staining and retains clarity over time

How easy are these containers to clean and maintain?

These glass containers are dishwasher safe for straightforward cleaning and won’t trap odors like plastic. For stubborn residues, a soak with warm water and gentle detergent restores cleanliness without harsh scrubbing.

• Top-rack dishwasher safe for hassle-free cleanup
• Non-porous glass resists staining and odor retention
• Simple hand-wash with mild detergent for longevity
• Dry thoroughly before stacking lids to prevent moisture buildup

Who this set is for: home cooks who prioritize food safety and want reusable, plastic-free storage; busy families and meal-preppers who need freezer-to-microwave convenience; and anyone seeking durable, attractive containers that keep kitchens organized. If you prefer storage that won’t leach chemicals, withstands heat, and cleans easily, the Ziruma beige 4-pack is designed to make daily meals safer and simpler.
