Thermo-Lunchbox – Lunchbox with insulation | Kalsten

The food is cold before you even take the first bite.

You took the time in the morning to prepare a warm meal – and by lunchtime, everything is lukewarm or cold. The Thermo Lunchbox keeps your food warm or cold for up to 4 hours thanks to its double-walled stainless steel insulation, so you can enjoy a truly warm meal during your break – whether it's soup, pasta, or rice. The leak-proof lid with silicone ring ensures that nothing ends up in your bag.

Advantages

• No more cold lunch breaks: Thanks to double-walled stainless steel insulation, your food stays warm for up to 4 hours – you open the box and it’s still steaming.
• No more wiping out your bag: The silicone ring and safety valve seal the box so reliably that liquids and sauces do not leak during transport.
• No questions about the safety of the material: The container is made of food-grade stainless steel 304 and PP – odorless, easy to care for, and reusable, so you don't have to worry about it.
