The Tefal MasterSeal Glass storage container made of borosilicate glass is a durable choice. Thanks to the unique lid seal, food stays fresh and crisp longer. Since the seal and lid fit tightly together, the container is completely hygienic. There are no gaps in the lid, preventing bacteria from growing. The lunch box is also completely leak-proof due to the lid sealing technology. The leak-proof storage container is ideal for transporting liquids and food. It is also odorless and hygienic, and it is free of BPA, making it suitable for baby food.

The storage container can withstand oven temperatures of up to 420 °C (without the lid). You can both cook the food, such as casserole dishes, and serve it at the dining table in the same container. If there are leftovers, you can conveniently just put the lid on and move the container to the refrigerator or freezer. The MasterSeal Glass storage container is also safe for microwave and dishwasher use. With its odor- and water-proof lid, it is excellent for marinating.
