I have these unadorned double wall glassware coffee mugs and use them everyday.  I am thrilled to see this beautiful holiday set with the snowflakes.  These mugs keep my coffee hot while the mug stays cool to the touch.  Every person I have gifted these mugs to always mentions that they use them everyday for their hot or cold beverages.  And what a great price for these.  Packaged two per box, it's really a great value and I solve two gifts with one purchase.
