FAQS
Can I put it in the dishwasher, freezer, oven and air fryer?

What temperature can the containers go in the oven?

What is the minimum temperature for the glass?

Can I go straight from freezer to oven or microwave?
Do not put the box into a preheated oven directly from freezer, always defrost before cooking to reduce thermal shock.
What is the maximum temperature change the glass will endure?
You should avoid sudden and severe temperature changes, ensure that you do not cause the glass to experience a thermal shock of more than 200°C (EN1183).
Do not place hot glass bases directly onto a cold or wet surface, such as a countertop or sink.
Do not place hot glass directly under running water.

Are the lids dishwasher-safe?

Are these compatible with the Black+Blum Stainless Steel Meal Prep Boxes?

Are these boxes leak proof?

How do I open the lid?
Push the button to release the lid lock and break the vacuum seal. Pull the lid upwards slowly for the easiest open.
Can I also microwave the lid?
Yes! We have specifically designed the lid to remove the need for single-use plastic cling film to prevent splatter when microwaving. Just ensure the lid lock is open to prevent pressure build up and to release steam, and you’re good to go.
