Stable, heavy stemware that will not get knocked over easily.  Great volume capacity.  Once you have ice in the glass, there is still room to hold plenty of your favorite beverage.  Coordinates well with other stemware in the collection.  Bubbles within the material add an interesting visual effect.

Pros: Heavy and because it is footed, does not leave a water mark on your table.
Cons: Even heavier when you add ice and liquid.
