the idea for xo, g was conceived in october 2013, when rancic discovered the stacktek, which consists of four prefilled, individually sealed, shatterproof, stemless wine glasses that snap together to form the equivalent of a 750ml bottle.  the clear outer sleeve of the packaging is decorated in white and silver xs and os, while a vibrant ribbon illustration wraps around the neck, adding a fun pop of color. making the wine accessible to women who appreciate style, quality and convenience was always rancic&39s goal.
