These clever space-saving containers can be used in the oven, making them perfect for cooking your food and then storing the leftovers in the fridge or freezer. Made from tough borosilicate glass. They re also thermal shock resistant meaning they can be used straight from freezer to oven. Like the rest of the Nest range, Nest Glass Storage can be stacked neatly together to save space when storing. Each coloured lid snaps tightly onto its container and features easy-pull tabs for opening. The lids also snap together when stored, making it extra easy to find them in your cupboard. Perfect for cooking and storing your sauces in the smallest container and up to an entire family meal in the bigger containers. Also great for saving on the washing up as only one container is needed.
