Packaging, labeling, warranties, and guarantees can be used as marketing tools. Packaging includes designing containers and comes in three layers - primary, secondary, and shipping packages. It should identify the brand, provide information, and protect the product. Labels identify the product, brand, grade, describe contents and producer. Warranties formally state expected performance and allow returns for repair. Guarantees reduce risk by suggesting quality and providing replacements, like Procter & Gamble's product satisfaction guarantee or A.T. Cross's pen replacement for life.
