These ruby red wine/cordial glasses are so beautifully red! The stems screw onto the glasses which have glass threads. One glass has the bottom of the threads broken, and the end of the threaded glass is stuck in the metal stem. There is still enough glass thread on the glass to screw in the metal stem and be safe and steady. Can also be glued with a strong glue for extra hold. This is a set of four glasses, four fluid ounce capacity, and they stand approx. 5.25" tall x 2 7/8" across the opening x 2 1/8" across the metal bottom. I will mark the broken glass before packaging.
