Beer stein or simply stein are English neologisms for either traditional beer mugs made out of stoneware, or specifically ornamental beer mugs that are usually sold as souvenirs or collectibles. Such Steins may be made out of stoneware (rarely the inferior earthenware), pewter, porcelain, or even silver, wood or crystal glass; they may have open tops or hinged pewter lids with a thumb-lever. Steins usually come in sizes of a half liter or a full liter (or comparable historic sizes). Like decorative tankards, they are often decorated in a nostalgic manner, but with allusions to Germany or Bavaria.
