Pump clips can be made of various materials. For beers that are brewed regularly by the big breweries, high quality plastic, metal or ceramic pump clips are used. Smaller breweries would use a printed plastic pump clip and for one-off beers laminated paper is used. There are variations on the material used, and the gaudiness or tastefulness of the decoration depending on how much the brewery wants to market their beers at the point of sale. Novelty pump clips have also been made of wood, slate and compact discs. Some even incorporate electronic flashing lights. Older pump clips were made of enamel.
