These mugs are really good looking. I have had another mug from a different team for several years. The mugs say that they are not to be microwaved. Of course, I do put them in the microwave to reheat my coffee. One day the emblem fell off, but I was able to find Elmer's Stix-All cement and it worked to bond the emblem back on the cup. The cement has lasted a year, so far.
