The Tefal MasterSeal Glass storage container made of borosilicate glass is a durable choice. Thanks to its unique lid seal, food stays fresh and crisp for longer. Because the seal and the lid fit tightly together, the container is completely hygienic. There are no gaps in the lid where bacteria could form. The lunchbox is also completely leak-proof due to the lid's sealing technology. The leak-proof storage container is perfect for transporting liquids and food. It is also odorless and hygienic and does not contain BPA, making it suitable for baby food.

The storage container can withstand oven temperatures of up to 420 °C (without the lid). You can easily cook food, like casseroles, and serve it at the dining table in the same container. If there are leftovers, you can conveniently place the lid on top and move the container to the refrigerator or freezer. The MasterSeal Glass storage container can also be used in the microwave and dishwasher. With its odor and water-tight lid, it is excellent for marinating.
