Advanced thermal insulation and 100% safety
The foundation of any high-quality thermos or thermal mug is the double-wall vacuum layer technology. This innovation prevents heat transfer between the inside of the container and the outside environment, ensuring that the exterior of the thermos will never get hot when filled with boiling tea, and will not sweat with condensation when holding ice-cold drinks. Utilizing SUS304 or SUS316 stainless steel, our containers do not retain the odors of previous beverages (unlike plastic ones) and are completely BPA-free, offering a perfectly healthy hydration experience.
How to choose the right thermal product for your needs
Although the core function is the same, the lid design and drinking system differ to adapt to various lifestyles.

DiscoverExpert Advice: Frequently Asked Questions
How long does a thermos keep a drink hot or cold?
Thermal performance depends on the volume and type of product. A 300-400ml thermal mug will keep coffee hot for about 4-6 hours. A classic, voluminous thermos (over 750ml), equipped with a special screw stopper, can keep liquids hot for up to 12-24 hours. Cold drinks (especially if ice cubes are added) are kept freezing cold for up to 24 hours in most of our stainless steel products.
Travel mug or classic thermos: which one should I choose?
If you drink your coffee or tea directly from the container while driving or walking to the office, a travel mug with a "click" opening is ideal, as it can be operated with one hand. If you need a larger quantity of hot liquid for an all-day hike and want to pour it into separate cups, choose the classic thermos with a cup-lid.
Are thermoses and thermal mugs dishwasher safe?
Generally, we recommend hand washing the main stainless steel body. The extreme temperatures in a dishwasher can degrade the vacuum seal between the container's walls over time, reducing its heat retention capacity. The lids and silicone gaskets, however, can usually be safely cleaned on the top rack of the dishwasher.
