A collection of small, often decorative devices, typically made of metal, that are connected to a keyring and usually depict beer-brand logos, beer bottles, or related items. They may also include beer tokens, which are special coins traditionally used for beer purchases, or beer mats, which are absorbent pads used to rest beer glasses. As part of the wider category of breweriana collectibles, these items are popular among beer enthusiasts and collectors of brewery-related memorabilia.
