Zulay Kitchen Food Storage Containers

While the borosilicate glass is heat-resistant and durable, it is best practice to let the container reach room temperature before placing it in a preheated oven to avoid thermal shock. Always ensure the lid is removed before heating in the oven or microwave.

The lids are designed to be both airtight and leak-proof. They feature a secure locking mechanism with a silicone seal that prevents liquids from spilling, making them reliable for transporting soups or dressings in your bag.

The containers are designed with a stackable profile, allowing you to nest them securely on top of one another. This helps maximize vertical space in your refrigerator or pantry shelves, keeping your storage area organized.

Yes, both the glass bases and the lids are dishwasher safe. For the best longevity of the silicone seals, we recommend placing the lids on the top rack.

Borosilicate glass is a type of glass that includes boron trioxide, which makes it significantly more resistant to thermal shock than standard soda-lime glass. This allows the containers to withstand rapid temperature changes without cracking or shattering.
