To avoid glass breakage caused by thermal shock, avoid pouring ice-cold liquid (or ice-cubes) into the flask right after its exposure to hot contents, and vice versa.
Do not use the flask lid to hold or drink beverages from it
The equipped stopper is not a water-tight device so avoid shaking or inverting the flask.
Keep the flask away from children especially if it contains hot liquid
The glass-vacuum products may keep content temperature for up to 24 hours when used as instructed.
Glass-vacuum containers can hold tea/coffee/Chinese medicine.
The imprints (‘black dots’) found in the glass inner are spacers between the double-wall surfaces; they will never touch the contents in a normal flask.
The highly reflective surface is achieved by the deposition of pure silver on the vacuum side of the glass inner; it will never touch the contents in a normal flask.
