How to use

Preheat or precool the flask by rinsing it with hot or cold water for a few minutes before filling to improve temperature retention. Unscrew the cap and pour in the beverage, leaving a small headspace if filling with very hot liquids to reduce pressure buildup. Close the screw cap tightly to ensure a proper seal. For pouring, open the cap and use the wide mouth to control flow; refill and reseal as needed. Clean after use by rinsing with warm water and mild detergent, and allow to air dry with the lid removed.

Usage recommendations

Do not use abrasive cleaners or scouring pads on the stainless-steel surface. Avoid dropping the flask from significant heights, which can compromise the vacuum insulation. For optimal performance, avoid storing perishable liquids for extended periods without refrigeration. Inspect the screw cap and seals regularly and replace if damaged to maintain leak resistance.
