Collateral material is the utility infielder of the marketing business. It's primary function is to describe the features of a product or service. Of course, the subtext always contains the benefits of the things. Specification sheets, catalogs and price sheets are the everyday data delivery systems that move products by giving prospective customers the basics of price and description. They are, by nature, utilitarian. But try hard not to ignore these materials. Without them nothing gets purchased.
