Cool & funny - Four colored glass cocktail coolers - made in Portugal. Iceballs are used to cool and decorate your drink. Put the iceballs in your freezer - make sure they don't touch each other and do not put them one on top of the other. As soon as the liquid content of the ball (non-toxic food aditive) has frozen use them to decorate any given drink. Before freezing them a second time, make sure the liquid has entirely melted. There were 6 in the box but 2 broke. For adults only.
