No-spill whiskey tumblers exhibit great design, both aesthetically and in function. Most of the variations of this glass have a nice, sleek curve, and the proportions necessary for the cup to prevent spillage also lends the cup to nice overall proportions. Thinking of the use of these tumblers, probably in a social context where people are drinking alcoholic beverages, having the feature of “no spill” is a good idea, especially as people may get increasingly more intoxicated! These are a luxury item, in the sense that they imply the ownership of whiskey, and other “classy” beverages, and also convey the fact that the owner is cognizant of entertaining her guests.
