Pressed on 12" Ultra Clear Heavy Vinyl. As the name implies, 'Heavy Vinyl' is heavier than regular vinyl coming in at 180G compared to 120G. With 'Heavy Vinyl' not only is the tactile satisfaction greater but so is the resulting durability and resistance to the inevitable degradation causing abuse which occurs over time. Some also argue that the sound quality is somewhat superior due to a more stable platform for your stylus and cantilever suspension. Cover sleeve has spine and is printed in full-color.
