This is a Vintage Danish "Kluk Kluk" clear glass whiskey/spirits decanter/bottle.  It is hand blown and was designed by Jacob Bang for Denmark's glass producer in Holmegaard. It makes a glug-glug sound as liquid is poured out of the various chambers which are inside the tear drop sections of the bottle.   It is approximately 13" tall including the round ball stopper and approximately 4.5" sq at base.  It is in very good condition with some residue on the top interior of the bottle. It is hand washable only. It would make a very unique addition to your collection as well as an excellent piece for use with your favorite beverage.
