Inspired by the shape and shimmer of bubbles, this set of four Bubble Rocking Tumblers is made from brilliant, highly durable, lead-free crystal glass and hand-painted with sheer, iridescent lustre. The bottoms of each glass are rounded, so they’re easier to hold and will gently rock on tabletops. Use the Bubble Rocking Tumblers to enjoy your favorite whiskeys, cognacs and cordials, or to serve mixed drinks or non-alcoholic beverages. Each tumbler holds 12 fl oz and measures 3h x 3.75”diam.
