he beautiful glass bottle is made of mouth-blown transparent glass, which makes it particularly decorative with either whisky or cognac in it on the bar trolley. The body of the spirits bottle has three columns. There are plenty of bottles on the market with four columns, but very few with three. The very special glug-glugging sound when the liquid is poured from the bottle and encounters the air in the bottle’s columns is the reason for its name in Danish, the “Kluk” bottle! This a great gift idea for that very special occasion.
