Bought this insulated tea flask / coffee mug for $7 @ Target.
Had a test run. Got my coffee from the local brista at round 9:30-ish in the morning (extra hot), and was still lukewarm at around 12 noon. Insulation wasn't the best, but good enough for a price like this. Three patterns to choose from.
I managed to get the Geo pattern (the LAST one left) from my local Target store.
seen similar things at Typo.
hw much do they cost there I wonder
