The Gold Series uses 24k double thick gold leaf to compliment and enhance the experience of even the finest spirits. Like our original Cube Glass, our Gold Series is designed to chill your beverage without the melted ice. Each wine glass is 4″H and comes with a solid-glass sphere fused inside. Store in your freezer and use to cool your favorite beverage. Pair seamlessly with our Gold Cube or Sphere Decanters.
