Abstract: A modular beverage-glass kit consists of a glass cup, a stem support structure, and a base support structure. The glass cup may have a cup portion and a male threaded portion. The cup portion and the threaded portion are integrally formed in one piece so as to resist accumulation of residue during washing. The stem support structure and the base support structure have different sizes and shapes but have the same female threaded portion for receiving the male threaded portion of the glass cup. The female threaded portion may be constructed separately and assembled into the support structure for improved manufacturing efficiency and flexibility of use. The components of the kit may be located in a box, such as a display case, for marketing and storage.
