Vtopmart Glass Containers

Yes, the borosilicate glass is designed to withstand extreme temperature changes, ranging from -4°F to 752°F. However, it is always best practice to avoid extreme thermal shock by letting the container sit at room temperature for a few minutes if moving from a deep freeze to a very hot oven.

No, the plastic lids are not oven or microwave safe. You should remove the lid before placing the glass container in the microwave or oven.

Yes, the silicone seals are removable, which makes it easy to clean out any trapped food particles or residue. We recommend removing them periodically to ensure a thorough wash and prevent mold buildup.

Yes, the 4-hinge snap-locking lids combined with the integrated silicone seal create an airtight, leak-proof barrier. They are secure enough to carry soups or dressings in a lunch bag without worrying about spills.

Yes, the containers are designed to nest within one another when not in use, and they stack securely when filled, helping you maximize your cabinet or refrigerator space.

Yes, all components of the Vtopmart glass containers, including the plastic lids and silicone seals, are BPA-free.
