The tumbler is characterized by its modular construction that can hold 20-ounces in its original mode, which can be expanded up to 40-ounces with a Boost module or 60-ounces with two. The tumbler also allows the Boost module to be paired with a separate bottom and lid to be used independently to maximize versatility. The Eureka tumbler is built with vacuum insulation and a copper lining that will keep beverages hot for up to 12-hours or cold for up to 24-hours. The cup is being launched as part of a Kickstarter campaign.
