The Travel Tumbler keeps drinks hot or cold for 6 hours! Fits snuggly (our term) into your side backpack pocket while on the go. Also features a "sip lid" so no ice cubes will aggressively hit your face while drinking.
Temperature tolerance: 45-156℉. For maximum insulation efficiency,
preheat or precool the tumbler prior to use by filling in a bit of hot/cold water for 1-2 minutes. Do not place in boiling water, microwave, or dishwasher. Handwash with care.
