Made from virtually unbreakable polycarbonate plastic these 10oz Elite Polycarbonate Nucleated Half Pint Tulip Tumblers are CE marked half pint to brim, with nucleated base which maintains a head on the beer, and offer a safe and practical alternative to glassware for bars, pubs, clubs or any outdoor event like festivals and sport events. More environmentally friendly than some disposable glasses, they can be washed and reused before being recycled at the end of their life.
