These are my favorite mugs of all time! I keep one in the freezer all the time, just in case. Wonderful for beer, heavenly for coffee or tea, even good for soup. They keep hot foods hot, cold foods cold. They are beautiful too look at, a brushed stainless steel. You can't go wrong with these folks and you will find more uses for them than you can imagine. At last, that cup of hot coffee will still be there when you return from cleaning up Jr.'s latest mess, walking the dog or running back downstairs to toss the laundry into the dryer and start another load. Just make sure you buy enough, because everyone will want one. Great gift too.
