A timeless classic the book may not be, but as far as well-titled pulp fiction goes it may be one of the best. If nothing else it is a humorous little joke that you can put on your keys! The keychains are made out of dense plastic with the image pressed into the finish. They are slightly smaller than the average business card. These keychains are hand-pressed in our small shop and because of the handmade nature of these products, there may be some slight differences between the one shown and the one you receive.
