| This two part shaker is preferred by professional bar tenders. How does it work you may ask? First add the ice then the non-alcoholic juices and ingredients and finally the ahem booze. Put the stainless steel container on firmly and hold as you shake the glass and steel container in a diagonal motion away from your body. Stop turn the shaker on its axis and shake again briefly but firmly. To open the shaker ease the top off by pulling upwards and turning firmly or tap the part below the join sharply against the edge of a table.Clear glass and 18/10 stainless steel Steel container is 3 3/4" Diameter x 6 1/4" H glass is 3 1/4" Diameter x 6" H Glass has oz. and cl markings holds 12 fluid ounces Dishwasher safe |
