These mugs not only look unique and trendy but they WORK!!!!
This mug keeps my capp hot !!!! Whereas traditional coffee mugs, my capp goes room temp quickly, whihc makes me not be able to sip and enjoy while I work but gulp it down!
They are very durable and not fragile in any kind of way.  I am impressed that it is LIGHTWEIGHT but durable!!!!!!
Both thumbs up!!!!!
