Rack 'em up and shoot them down! A playful way to serve shots to a crowd, in this amazing, billiards shot glass set. Ever thought that pool balls are the perfect size to hold a shot glass, if their top was cut off? Ok, so we may be in the minority on that one but it seems pool balls may have found their second calling as a holder for your drink. The different coloured pool ball holders come in a box with a set of 9 shot glasses. With a sturdy, flat base, the holders will carry each shot glass upright, without fear of tumbling.
