The slight difference in proportion to our standard 28oz Weighted Cocktail Shaker makes all the difference to working and performance flair bartenders. Made of the same quality stainless steel, and just as ideal for mixing drinks behind the bar or at home, these flair cocktail shaker tins are guaranteed to have a 93mm diameter at the opening which provides consistent throws and stacking without the dreaded "sticky" shakers. For reliable shakers built with performance in mind, you've got to stock up with these!
