These are absolutely the most beautiful and unique crystal tumblers I have ever seen. So happy I didn't heed the other reviewer's negative comments. If you want common, bland glassware, these aren't for you. These tumblers are a good, heavy weight with a stunning assymetrical 'crystalline' design that really sparkles against our Rosso Levanto marble vanity in the lights of our master bathroom (great that it came as a pair; a bathroom tumbler for each of us... ). I know they're expensive, but I'm thinking about purchasing a set of 8 or 10 for our bar; they really are that beautiful! Very well made, gorgeous packaging, and would make a great gift... (No I don't have any affiliation with the seller/manufacturer, but I just thought that these we're not being fairly reviewed.) We love these 'Sculpture' tumblers!!!
