The Tefal MasterSeal glass storage container made of borosilicate glass is a durable choice. Thanks to its unique lid seal, food stays fresh and crispy longer. Since the seal and lid are tightly fitted, the container is completely hygienic with no gaps where bacteria can grow. The lunch box is also completely leak-proof due to the lid sealing technology, making it great for transporting liquids and food. It is odorless and hygienic, and contains no BPA, making it suitable for baby food.

The storage container can withstand oven temperatures up to 420 °C (without the lid). You can prepare dishes like casseroles and serve them directly on the dining table in the same container. If there are leftovers, simply place the lid on top and move the container to the refrigerator or freezer. The MasterSeal glass storage container can also be placed in the microwave and dishwasher. With its odor- and water-tight lid, it is excellent for marinating.
