Q: How long does the stainless steel thermos keep drinks hot or cold?

A: Thanks to its vacuum double-wall insulation, this smart tumbler maintains hot beverages for up to 12 hours and cold beverages for up to 24 hours, depending on ambient conditions and how frequently the lid is opened.

Q: Is this travel mug leakproof — can I put it in my bag?

A: Yes! The lid features an airtight food-grade silicone seal designed to prevent spills and leaks, making it completely safe to carry in a bag, backpack, or car cup holder. The non-slip rubber base also keeps it stable on any flat surface.

Q: Which size should I choose — 380ml or 510ml?

A: The 380ml size is ideal for a standard coffee or tea serving and fits most standard cup holders. The 510ml size is great if you prefer a larger beverage or want extra capacity for longer trips. Both sizes share the same premium build and insulation performance.
