Can I put the lids in the oven or microwave?

No, always remove the lids before using containers in the oven or microwave. The borosilicate glass containers are safe from -40℉ to 752℉, but the lids with silicone seals should only be used for storage. This protects the airtight seal and extends the life of your lids.

Will these containers leak in my bag?

The locking lids create an airtight seal that prevents leaks when properly closed. You'll feel the tension when you snap the four-sided locks into place—that's what keeps liquids secure. Perfect for soups, sauces, and dressings in lunch bags or gym bags.

How do I clean and care for these containers?

Glass containers are dishwasher safe and won't stain or retain odors. For best results, hand-wash the lids to protect the silicone seals and extend their lifespan. The smooth glass surface rinses clean in seconds without scrubbing, even after storing tomato-based sauces.

Do the containers really nest inside each other?

Yes, smaller containers nest inside larger ones within each shape family (rectangle, square, and round). This nested design saves significant cabinet space when not in use. The lids stack separately, keeping your storage area organized and clutter-free.

Why you'll love it

This 18-piece glass storage set gives you the versatility to handle any kitchen task—from meal prep to leftover storage to ingredient organization. With three distinct shapes and nine different capacities, you'll always have the right size container.

Three shapes for every need: Rectangle containers for casseroles and layered meals, square for perfect portions, round for soups and sauces
True temperature versatility: Borosilicate glass goes from -40℉ freezer to 752℉ oven without cracking or warping
Airtight locking lids: Four-sided locks create a leak-proof seal that keeps food fresh longer and prevents spills
Space-saving design: Nested storage means your nine containers take up minimal cabinet space when not in use

How to use

Select the appropriate container size for your meal or ingredient. Fill with food, leaving a small gap at the top for expansion if freezing. Snap all four sides of the locking lid into place until you feel resistance—this creates the airtight seal.

For reheating, remove the lid completely before placing the glass container in the microwave or oven. After use, wash glass containers in the dishwasher and hand-wash lids to preserve the silicone seals. Nest smaller containers inside larger ones and stack lids separately for organized storage.
