Glasslock Food Storage Containers

Yes, these containers are crafted with Temperamax technology, making them safe for oven use. However, avoid placing cold glass directly into a very hot oven to prevent thermal shock, and ensure the plastic lids are removed before heating.

No, only the glass containers are oven and microwave safe. You should remove the plastic lids before heating your food to prevent warping or melting.

While the containers are stackable when filled with lids on, they do not nest perfectly inside one another due to their rigid glass construction. You will need to dedicate some cabinet space to store them, though their square and rectangular shapes help maximize that footprint.

The lids are designed for a secure, comfortable fit that keeps food fresh. While they are excellent for standard refrigerator storage, they are not intended to be completely leak-proof for carrying liquids like soups in a bag.

Yes, both the glass containers and the plastic lids are dishwasher safe. We recommend placing the lids on the top rack to maintain their shape and longevity.

Yes, all components of this set, including the glass containers and the plastic lids, are constructed from BPA-free materials, ensuring no harmful chemicals leach into your food.
