Black + Blum Stack + Nest Glass Food Containers - Set of 5
The Black and Blum Stack and Nest Glass Food Container set of five is built for households that meal prep in volume or want enough containers to cover a full week of lunches without running out. Each container is made from borosilicate glass with a vacuum-sealed, leak-proof lid and a fully removable silicone seal for thorough cleaning. The same set of features applies as the three-container version: safe across the freezer at minus 20 degrees C, oven and air fryer at up to 250 degrees C, microwave, and dishwasher. Containers of the same size stack directly on top of each other; different sizes nest inside one another for compact cupboard storage. The set of five is available in Small (600ml) and Medium (900ml), and is 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. A set of five in a single size stacks into a compact column that takes up minimal cupboard space.
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:
Why choose the set of five rather than the set of three?
The set of five makes more sense if you meal prep for a full working week in one session, cook in larger batches, or want enough containers to cover multiple people's lunches simultaneously. The per-container cost is also lower in the set of five compared to buying two sets of three. Note that the five-container set is only available in Small (600ml) and Medium (900ml), whereas the three-container set also comes in Extra Small and Large.
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. 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. Remove the silicone seal before washing to ensure both the lid and seal are cleaned properly. The seal can go in the dishwasher or be washed by hand.
Are these also available individually or in sets of three?
Yes. Each size is available individually and in sets of three. The three-container set also comes in Extra Small (380ml) and Large (1.2 litres), which are not available in the five-container set.
