Hand-cut in Turkey for Sir/Madam, heavy in the bottom, easy in the hand, with a cut edge that reads modern without turning clinical. Two to a set, because you rarely pour for yourself. In Powder, a soft blue, or Tuxedo, a black-and-white edge.

For the host who already knows how to make an Old Fashioned.
