This versatile food storage container set combines thickened borosilicate glass bodies with negative-pressure plastic lids for reliable freshness. Square and round sizes support organized storage of leftovers, fruits, vegetables, snacks, soups, and prepared meals. Pressing the lid creates an airtight seal, while the built-in vent allows easy opening after refrigeration. Transparent glass helps users identify contents quickly, and the stackable design saves refrigerator and cabinet space. BPA-free materials meet FDA and LFGB food-contact standards. The glass containers are suitable for refrigeration, freezing, dishwasher cleaning, and microwave reheating after removing the lids, making them practical for modern households and meal preparation.

This versatile glass container set consists of square and round vessels crafted from premium borosilicate glass, paired with innovative negative-pressure plastic lids. Simple pressing creates airtight environments to slow food deterioration. Graduated sizes support classified food storage, and stackable construction maximizes refrigerator space. Free of harmful additives, these containers serve weekly meal preparation, leftover preservation and fresh produce storage for modern families.
1. The upgraded plastic lid adopts negative pressure sealing technology. Press the lid manually to discharge internal air and form a tight seal without complicated locking buckles. This design effectively suppresses bacterial reproduction and prevents cross-flavor pollution inside refrigerators. The built-in vent structure easily releases pressure when users need to open containers.
2. The container body uses thickened high borosilicate glass with excellent thermal shock resistance. The compact non-porous surface hardly absorbs grease, pigment and food odors. Unlike plastic alternatives, it will not age or release hazardous substances after repeated use. It adapts to refrigeration, freezing and moderate microwave heating for diversified daily use.
3. The set includes square and round container series with progressive volumes. Square models make full use of refrigerator corner space, while round containers fit fruits, soups and semi-liquid food. All containers can be stacked vertically to reduce cabinet occupancy. Users can freely match specifications according to different food categories.
4. Clear glass structure enables users to identify stored food instantly without opening lids. This avoids frequent unpacking and maintains stable internal sealing conditions. Smooth inner walls reduce food adhesion, greatly lowering cleaning difficulty. The minimalist neutral-toned lids match various kitchen decoration styles.
5. All food-contact materials comply with LFGB and FDA standards and contain zero BPA. The glass withstands temperature fluctuations from freezing to moderate heating. Lightweight and sturdy construction supports daily indoor storage. It is reusable for long periods and helps cut waste generated by disposable packaging.

Sort fresh fruits, vegetables, cooked leftovers and pickled ingredients inside refrigerators. Independent containers isolate strong-flavor food and avoid odor mixing. The stackable layout optimizes limited shelf space. Transparent glass lets you quickly check stored food and reduce unnecessary waste caused by forgotten ingredients.
Portion pre-cooked staple food, vegetables and protein in advance for daily lunches. Reliable sealing keeps food fresh during refrigeration. Different sizes satisfy different portion demands. Containers can be directly used for microwave reheating after removing lids, simplifying dining arrangements for busy commuters.
Small-sized containers are suitable for storing nuts, candies, grains and homemade preserves. Negative pressure sealing blocks moisture in the air to prevent dry food from dampening and spoiling. Stackable design keeps kitchen cabinets neat, replacing messy disposable plastic bags for cleaner long-term storage.
Lightweight glass containers can hold salads, cut fruits and homemade snacks for outings. The sealed lids effectively reduce liquid leakage during transportation. Multiple independent boxes separate different foods. The reusable design offers an eco-friendly alternative to disposable lunch boxes for family outdoor activities.
Clean and dry containers before first use. Place food into the glass vessel, cover the plastic lid and press down firmly to build negative pressure sealing. Lift the built-in vent tab to release air pressure when you need to open the lid. Remove lids before microwave heating. Avoid sharp tools scratching the glass surface during cleaning.
The borosilicate glass body supports microwave heating, but you must take off the plastic negative-pressure lid. High temperature will deform the plastic lid and damage the internal sealing structure. Do not conduct empty heating to prevent glass cracks.
Temperature drop enhances the negative pressure inside the container, leading to tighter sealing. Simply pull up the vent valve on the lid to balance internal and external air pressure. After air flows in, you can easily lift the lid without excessive force.
High borosilicate glass has a dense non-porous structure and rarely absorbs odors. Nevertheless, strongly seasoned food should not be sealed for over 48 hours. Clean the container promptly after use to maintain lasting freshness.
Yes, flat lid surfaces support stable vertical stacking. Try to place larger containers at the bottom. Avoid placing heavy items on top of small containers, as excessive pressure may affect negative pressure sealing performance and cause accidental loosening.
