Ziruma Non-Toxic Glass Food Storage 4 Pack - Plastic Free Meal Prep

In this review the Ziruma Non-Toxic 4 Pack earns its place for cooks and families who want truly plastic-free storage. The single biggest reason to buy is the promise of total purity: lids and containers are made from 100% borosilicate glass so nothing plastic touches stored food. That matters for anyone avoiding BPA, plastic taste, or chemicals leaching into meals. The set covers everyday needs from snacks to full meals and is aimed at people who prep, freeze, reheat and want airtight, dishwasher-safe containers that move straight from fridge to oven or microwave.

Key Features

• 100% Borosilicate Glass: Both containers and lids are glass, providing a plastic-free contact surface to protect food from chemical contamination.
• Four Sizes Included: The 12 oz, 21 oz, 35 oz and 50 oz sizes give flexible portioning for snacks, lunches and family meals without needing extra containers.
• Airtight Seal: The lids form a tight, leakproof seal to keep air out so food stays fresher and flavors are preserved longer.
• Heat and Freeze Safe: These containers handle freezer storage, microwave reheating and oven use, which reduces dish changes and speeds meal routines.
• Dishwasher Safe: Reusable and easy to clean in the dishwasher, saving time on maintenance after heavy meal prep days.
• Leak Prevention: The design aims to prevent spills so soups and sauces can be transported without mess when the seal performs as intended.

Who It's For

This set is ideal for health-conscious cooks, busy families and anyone who wants to eliminate plastic contact with food. Meal preppers who portion lunches for the week will appreciate the range from 12 oz to 50 oz and the ability to freeze, reheat and serve from the same container.

Those who primarily need ultra-lightweight containers for backpacking or want single-handed, soft-sided lids should look elsewhere, since borosilicate glass is heavier and the lids are rigid. If you require perfect seal performance for long, vigorous transport, test the seal with the exact foods you carry, as seal impressions among users are mixed.
