16oz Yay All Day in Gold Letters Mug Set. This listing is for a set of 2 (2-pack) of 16oz coffee/tea mugs. They are very pretty. The gold accents make them perfect for displaying them on your coffee bar. Although they don't have the original tickets, these mugs have never been used. We only used them as decoration on our coffee bar. Note: Due to the gold details, they are NOT microwave safe. They are, however, dishwasher safe.
