Designed for serving Irish coffee in style, this delicate-looking glassware surely makes the hot concoction even more tempting. The non-tempered glass construction means this mug isn"t as tough as those with tempered glasses, but the thick construction somewhat compensates for this. This superb glassware made by Cardinal is available in sets of 24 under item code ca-53403. 10 oz., 5-5/8" high. (Old Model # 30-53403 )
