Durable borosilicate glass food storage containers are built to handle extreme temperatures from -4°F to 950°F, making them safe for oven, microwave, and freezer use. The set includes five large 1040ml and five small 370ml containers, ideal for meal prep, storing leftovers, or organizing pantry items. Clear glass construction allows quick identification of contents while the stackable design helps save space in cabinets or refrigerators. Each container features a snap-on tempered lid with an air-release valve that ensures a secure, leak-proof seal yet remains easy to open. These containers support even heating and prevent flavor transfer, enhancing food quality during reheating. Their robust build resists thermal shock and daily wear, suitable for consistent home use. Though dishwasher safe for convenience, hand washing lids is recommended to extend longevity. The minimalist aesthetic fits seamlessly into modern kitchens, and the practical sizing works well for portion control, lunch packing, or ingredient storage. Free of branding and marketing language, these containers focus on function, durability, and versatility across a range of kitchen tasks without compromising safety or performance. Color: Blue.
