The StackTek 100-CUB is a 7 oz stemless plastic tasting glass engineered to replicate the look and feel of real glassware while delivering the portability and durability that busy service environments demand. Built from 100% BPA-free, shatterproof plastic, these cups are fully recyclable and reusable, making them an eco-conscious choice for wineries, tasting rooms, caterers, and event operators. StackTek’s patented interlocking snapping mechanism allows cups to lock together securely, eliminating spills during transport and simplifying storage. Each cup holds exactly one-quarter of a standard 750mL wine bottle, making portion control and flight service seamless. Frost-colored lids are included with every glass, keeping contents secure whether the cups are being served, stored, or carried to go.
