Q: How can leakage be avoided?

Q: Why does the received kettle have water mist inside and rust-looking spots on the nozzle?

A: To ensure a usable kettle, we conduct a water spray test in the warehouse, causing some water vapor. Nozzle spots are water stains, not rust—normal. In later tests, we aim for a more satisfactory kettle.

Q: What's the reason behind the presence of mold?
