- No! That’s just the sealing mark from vacuuming. https://www.umbottle.com/ProductsDetail-VB-10486.htmlThe insulation layer remains intact. But if the dot is visibly dented or rusty, be cautious.

Q: How can I test insulation performance?

- DIY test: Fill with 95°C hot water. If the temperature stays ≥65°C after 6 hours, it’s qualified; ≥75°C is excellent.
