I ordered the 20oz Tumbler and the 16oz. They look amazing and appear to be well made. They keep my hot tea warm for hours and the graphics on the tumblers look awesome. I remember buying "Back In Black" back in the Summer of 1980 when it first came out. I played it so much that i wore the record out. My favorite AC/DC album is "Highway To Hell" but "Back In Black" is probably my 2nd favorite. cheers.
