Ziruma Non-Toxic 2.6 Cup Glass Food Storage Containers - Plastic Free

In this review of the Ziruma non-toxic 2.6 cup glass food storage containers, the bottom line is simple: these containers are for cooks and families who want truly plastic-free storage without sacrificing convenience. The reviewer found the set especially strong for soups, stews, and meal prep because each 21 oz container and its lid are made from 100% borosilicate glass, offering a clear benefit for anyone worried about plastic contact with food. The airtight, leakproof lids aim to keep flavors locked in, and the ability to go from freezer to microwave and oven adds real everyday value.

Key Features

• Plastic-free construction: Made from 100% borosilicate glass including the lids, these containers remove any plastic contact with food for cleaner storage.
• Right-sized for comfort foods: At 21 oz (2.6 cups) each, the containers are well suited for soups, stews, broths, and single-portion meals for meal prep.
• Airtight glass lids: The lids are designed to seal out air and contaminants to help preserve freshness and lock in flavors.
• Leakproof design: The tight, leakproof seal makes these containers practical for packing liquids and sauces without worrying about spills.
• Heat and cold safe: Safe for the freezer, microwave and oven, which allows storing, reheating and serving from the same dish for convenience.
• Dishwasher safe: The glass construction cleans easily in the dishwasher so there is minimal scrubbing after use.

Who It's For

These containers are ideal for home cooks, busy families, and anyone focused on eliminating plastic from food contact points. If you regularly prepare soups, single-portion meals, or batch-cook for the week, the 21 oz size and airtight lids make these a practical choice for meal prep and refrigerated storage.

Shoppers who need very small portion containers, or who prefer ultra-lightweight plastic for backpacking, should look elsewhere; the glass construction is heavier and better suited to kitchen use rather than rugged travel. Those who require multi-compartment bento-style lunchboxes will also find single-cavity glass less convenient.
