Stainless steel double wall with air gap makes it isothermal. Compact and lightweight with a wide opening. Its soft handle and screw-on lid make it practical. (0.5 liter).
Need to keep your food warm (or cold) for a few hours? Our designers have developed this simple and lightweight stainless steel isothermal box.
Advice for maximizing the performance of your isothermal box.
Fill your food box with hot water for 5 minutes, then replace the water with your hot food. Close the box.
The fuller the box, the more effectively it keeps its contents hot or cold. This box has a smaller volume and won’t stay warm as long as a larger, full box. Go for the 0.8 L model if you want the most isothermal product.
Functions
This simple product is made up of 4 components (stainless steel tank, separate polypropylene lid, silicon seal, and handle) that can be separated if need be.
We opted for a fairly wide 3.1″ diameter opening to make washing and filling the box easier.
The soft handle makes it easy to carry without taking up space once in your bag.
Do not place in the microwave.
Care tips
Dishwasher safe product (lid + body). Warning: In this case, do not lose the top seal. Dry with the top off. The seal and handle can be removed for a complete wash and dry.
1st use
Rinse the entire product 3 times with clear water before using for the 1st time.
Materials and regulations
Our products and materials meet the food-contact standards in effect. They do not contain Bisphenol A (BPA) in accordance with the French regulations in force.We have chosen to use 18/8 (304) stainless steel for the tank, recognized for its food safety, and a heat- and shock-resistant polypropylene for the top. The seal and handle are made from silicon, an extremely durable material.

How does the isothermal element work?
We use a double stainless wall with a vacuum between to block thermal exchanges by conduction or convection. To block exchanges by thermal radiation, a fine layer of copper covers the outside of the inner wall. The top is insulated with an internal insert made from expanded polystyrene.
Top tips…
As well as keeping food warm, you can also keep it chilled on your hikes. Thereβs nothing better than a spoon of ice cream halfway through your walk to motivate the kids (and the grown-ups!).
You can also use your box as a yogurt maker: Bring the milk to the boil, leave it to cool down to around 109Β°F (warm but doesnβt burn), then pour the milk into the box with a spoon of yogurt. Close the box and leave overnight (between 6 and 10 hours).

The product is also guaranteed for 5 years in normal use conditions.
Our environmental approach (2/2)
We also selected:
– Solvent-free laser-engraved branding.
– Solvent-free paint (powder coating) to give texture to reduce condensation and improve grip.
– Maximum reduction in packaging and transport packaging.
– Factory manufacture using 100% renewable energy.
