Usage recommendations

For optimal thermal performance, fill the flask as much as possible to reduce air volume inside. Clean the thermos after each use with warm soapy water and rinse thoroughly. Do not use the thermos for carbonated drinks or perishable food that requires refrigeration. Check lid seals regularly and replace if worn to maintain airtight performance.
