Tai sis a fun old mid-century cocktail shaker with muddler that was made by Kamkap Inc, USA as marked on the underside of the glass shaker, which also indicates the the red and black bands indicate 4-8-12 oz and the total capacity is 20 oz. It is in very good condition with no damage to the very heavy and sturdy piece of glass an nice color on the bands. The top and muddler are also heavy well made pieces and the chrome is in great shape. There is a little use wear on the bottom of the muddler but that is to be expected. It stands almost 9.25 inches tall and displays beautifully. This is neat barware or kitchenware for that retro kitchen!
