Meet the BeerNStein™ – a 24oz capacity insulated beer tumbler inspired by the classic German-style beer stein. That’s right – Two 12oz beers = 1 BeerNStein, making it convenient to fill up and bring for a relaxing time at the pool or beach. The BeerNStein tumbler is made of Acrylonitrile Styrene (AS), an upgraded plastic material that is top rack dishwasher approved. Although the BeerNStein can be enjoyed with or without the lid – each BeerNStein™ includes an accompanying ABS lid with rubber gasket. Patent Pending by The Product Farm. Designed in the USA. Made in China.
