Jiggers are small hourglass shaped spirit measures which help in pouring the exact amount of liquor into glasses. With 2 measures on each end of the Jigger, preparing drinks is sped up dramatically. Marked with both 20ml and 40ml and 10ml and 30ml increments, this really is a versatile piece of equipment. Its trendy stainless steel finish makes this jigger stand out on any bar.
