Let's offer up an apology to Messrs Hammerstein and Kern, then start off with all the things they aren't: heavy (weight is 3.8 oz. Troy each), perfect (see third photo), finest quality, or antique. So they are? Cheap, rather elegant looking, and guaranteed to hold whatever liquid you might choose to imbibe. Height 3 7/8 inches.
