Black + Blum Stack + Nest Glass Food Containers - Set of 3
The Black and Blum Stack and Nest Glass Food Containers are designed to solve the two main frustrations with food storage: lids that do not seal reliably and containers that take over an entire cupboard. The airtight, leak-proof lid uses a vacuum-sealed lock to keep food genuinely fresh, with a fully removable silicone seal that makes the lid easy to clean properly. The containers are made from borosilicate glass, which handles the full range from freezer at minus 20 degrees C to oven and air fryer at 250 degrees C, and are dishwasher and microwave safe too. Containers of the same size stack directly; different sizes nest inside each other. Each set contains three containers of the same size, available in Extra Small (380ml), Small (600ml), Medium (900ml), and Large (1.2 litres), and they are compatible with Black and Blum's stainless steel Meal Prep Boxes.
Features:
Borosilicate glass construction: High-quality borosilicate glass handles temperatures from minus 20 degrees C to 250 degrees C, making each container safe across the freezer, fridge, oven, air fryer, and microwave without needing to transfer food between vessels.
Airtight, leak-proof lid: The vacuum-sealed lid lock creates an airtight seal that keeps food fresh for longer and prevents leaks, making the containers reliable for transporting food as well as storing it.
Fully removable silicone seal: The silicone seal lifts out of the lid completely for cleaning, removing the main source of residue build-up and odour transfer that affects most food storage lids over time.
Stack and nest design: Containers of the same size stack directly on top of each other; different sizes nest inside one another. Either way, the set takes up significantly less cupboard space than a conventional container collection.
Compatible with all main kitchen appliances: Each container is rated dishwasher, oven, air fryer, microwave, and freezer safe, and is compatible with Black and Blum's stainless steel Meal Prep Boxes for use across different preparation methods.

Care instructions:
After each use: Wash the container and lid in the dishwasher or by hand with warm soapy water. Remove the silicone seal from the lid before washing to ensure both parts are cleaned properly.
Silicone seal: Remove the seal after each use and wash separately. Check periodically that it is seated correctly when refitting, as a poorly fitted seal will affect the airtight performance.
Oven and air fryer use: The glass body can go in the oven or air fryer up to 250 degrees C. Do not put the lid or silicone seal in the oven or air fryer. If going from cold storage to a hot oven, allow the container to reach room temperature first.
What to avoid: Do not drop the containers on hard floors. Do not use abrasive scourers on the glass. Do not place directly from a very cold freezer into a hot oven without allowing time to acclimatise first.
Questions and answers:
Can I put these directly from the freezer into the oven?
Borosilicate glass is significantly more resistant to thermal shock than standard glass, but moving directly from a very cold freezer to a hot oven is still not recommended for any glass container. Allow the containers to come to room temperature first before placing in a hot oven to avoid any risk of cracking.
Does the lid go in the dishwasher as well as the glass?
Yes, the lids are dishwasher safe. The silicone seal should be removed before washing to ensure both the lid and seal are cleaned properly. The seal can be washed in the dishwasher or by hand.
What is the difference between stacking and nesting?
Stacking is placing containers of the same size directly on top of each other, which works well in the fridge or when transporting meals. Nesting is fitting different sizes inside each other for compact storage in a cupboard when not in use. The Stack and Nest design is shaped to do both efficiently.
Are these also available individually or in larger sets?
Yes. Each size is also available individually and in sets of five. If you want to mix sizes, buying individual containers from the range lets you build a set that suits your specific storage needs.
