Better Materials Around Your Food
Your food comes into direct contact with 304 (18/8) food-grade stainless steel rather than plastic. That means:
The removable silicone seal is the only non-stainless-steel component. It sits inside the lid to make the metal lunch box leakproof and does not touch your food. The silicone is REACH compliant and tested according to EU requirements for restricted substances.
Less plastic around what you eat, with materials made to last.
Clean, Durable Materials You Can Trust
304 (18/8) food-grade stainless steel: Used for the body, lid and divider. It is sturdy, corrosion-resistant and helps preserve the taste of your food without plastic contact.
Food-grade silicone seal: Sits inside the lid to create a secure and leakproof closure. The seal is removable, making it easier to clean thoroughly and complies with REACH requirements for restricted substances.
Removable stainless steel divider: Turns the box into a lunch box with compartments when you want foods separated. Remove it whenever you need one larger space.
No inner lining or coating: Your food comes into direct contact with stainless steel, with no plastic lining inside the lunch box.
Tested free from lead and phthalates: The tested food-contact materials do not contain these substances of health concern.
Is the stainless steel lunch box leakproof?
Yes. The stainless steel lunch box uses a removable food-grade silicone seal inside the lid to create a secure and leakproof closure.
That means you can carry your lunch in a work bag, backpack or school lunch box bag with more confidence.
Does the lunch box come with compartments?
Yes. Each lunch box includes one removable adjustable divider that creates 2 sections for different foods.
Use it as a lunch box with compartments when you want to keep foods apart, or remove the divider when you need one larger space.
What sizes does the lunch box come in?
The lunch box is available in 3 sizes:
- 800 ml for smaller snacks
- 1200 ml for everyday lunch
- 1400 ml for larger meals
The different sizes make it easy to choose a kids lunch box, everyday work lunch box or larger meal prep container depending on how much you usually pack.
Is the stainless steel lunch box dishwasher safe?
Yes. The metal lunch box is dishwasher safe.
Before washing, remove the silicone seal and clean it separately by hand. This lets you clean thoroughly around the lid and helps prevent food from getting trapped between the seal and the metal.
Can I put the lunch box in the oven?
Yes. The bottom stainless steel container is oven-safe, so you can use it to heat or cook food.
Always remove the lid before putting the lunch box in the oven. This prevents pressure from building inside the closed container and ensures the silicone seal never goes into the oven.
Can I microwave the stainless steel lunch box?
No. Stainless steel cannot be used in the microwave.
To reheat your meal, either use the oven-safe stainless steel bottom without the lid or transfer your food to a microwave-safe plate or container.
Does the lunch box keep food warm?
No. The lunch box is not insulated, so it is not designed to keep food hot or cold for extended periods.
I can't open my lunch box anymore. What should I do?
If you close the lunch box while the food is still hot, the air inside can cool and create a vacuum effect, making the lid difficult to open.
Gently lift one side of the lid to let a little air in, then try opening it again.
To help prevent this, let hot food cool slightly before closing the lid and refrigerate it once it has cooled enough.
What certifications do the lunch box materials have?
Every material used around your food are independently tested and meet EU food-safety requirements.
Our lunch boxes are made from 304 (18/8) food-grade stainless steel, with a silicone seal in the lid. That means only stainless steel touches your food.
Here is what the tests cover:
- EU 1935/2004 compliant: verifies that the materials do not leach substances into your food and do not alter its taste or smell.
- REACH-compliant silicone seal: confirms that the silicone complies with EU restrictions for restricted chemical substances.
- Free from lead and phthalates test: guarantees that the tested food-contact materials do not contain these substances of health concern.
