We’re shaking up the cocktail shaker market with a patented Flip-Top mechanism that does away with the usual separate strainer. The Houdini Flip-Top Shaker opens and closes with the touch of a finger. Two years in development, it’s a feat of hydraulic engineering applied to hi-tech sealing materials. The “Flip-Top” is double-walled plastic, so it’s never cold to the touch. It’s the first real innovation in cocktail shakers since Prohibition.
