SIAZIH Glass Food Storage Container Set with Lids, 370/640/1040/1520ml, Dishwasher, Microwave, Freezer Safe, Leakproof, BPA Free

Glass Containers with Lids: These food glass containers are great for storing and transporting food, even on picnics and camping trips. They are also great for use in restaurants, homes, offices, schools, and gyms

Steam Valve: A mechanism that regulates temperature differences and prevents air condensation. The valve prevents water vapor from accumulating inside the container, which prevents food from becoming soft, dry, or losing flavor. Glass food storage containers are -20℃ to 400℃ resistant. Microwave/Oven/Dishwasher safe (lid not included).

Airtight, Leakproof Storage Containers and Space Saver: BPA-free, securely lockable plastic lids with silicone rings ensure a tight, airtight, and waterproof seal, keeping food fresher longer. No more leaks. Stackable small food storage containers can be stored inside large food storage containers.

High-quality Borosilicate Glass: The food containers are made of high-quality borosilicate glass, which is stain-resistant, odor-resistant, corrosion-resistant, and extremely durable. It is stronger and more resistant to temperature fluctuations than ordinary food storage containers. They are easy to use and clean, just put them in the dishwasher or rinse them under running water
