How to use

Pre-warm or pre-chill the flask by rinsing with hot or cold water for a few minutes before filling to improve thermal retention. Fill with the desired beverage and securely close the lid to maintain insulation. For best results, avoid frequent opening when temperature retention is required. Clean the flask after use following the manufacturer's care instructions, typically by rinsing with warm soapy water and allowing to air dry.

Recommendations

Do not place the flask in a microwave. Avoid using abrasive cleaners or steel wool on the exterior to preserve the stainless steel finish. For prolonged temperature retention, pre-condition the flask and keep it closed until consumption. Hand wash recommended to maintain seals and insulation performance.
