Slightly wider top and optic glass combine beautifully to present Irish coffees in a different, more visually appealing way - the optic glass magnifies the contents, while the wide opening gives a good view of the rich cream topping. The attractive design of this Libbey mug also features a layered stem and a smallish handle. This item is sold in sets of 24 under product code lg-5294. Top diameter 3.125", bottom diameter 2.75"
