Are you still using ice in your shaken, but not stirred martinis? Come on, it's the 21st century, and ice is no longer necessary. Check out the Nambe Twist Cocktail Shaker and matching Nambe Twist Martini Glass. Both are made of the incredible thermal-retentive Nambe metal which has 3X the cold retention of common metals. Just place in your freezer for 30 minutes to properly chill. Gotta love that teardrop helix design as well. Cool, literally.
