What is a stainless steel thermos flask?

Stainless steel thermos flasks are drinking bottles made of stainless steel. Stainless steel comes in many different qualities. We use the highest quality stainless steel that can be used for thermos flasks, namely 304 stainless steel.

What are the benefits of stainless steel drinking bottles?

Stainless steel has a lot of advantages. For example, it keeps out heat and cold very well. Heat and cold that are in the bottle will not escape quickly, so that your drinks stay hot or cold for a very long time. In addition, it does not absorb any taste. So you can first drink coffee from your thermos and you will no longer taste this coffee after you have rinsed the bottle once.

Can a stainless steel bottle rust?

No, stainless steel drinking bottles cannot rust. However, if a bottle is not properly maintained, something called 'fly rust' can develop. This is not rust, but looks very similar. However, this is very easy to remove using a scouring pad, hot water and some cleaning agent.
