Professionalgrade construction: Made from foodgrade 304 stainless steel for longlasting use in both home and commercial settings. Unlike glass shakers, these allstainless tins won't crack or shatter, and there is no rubber seal to dry, crack, or warp over time. Dishwasher safe: Clean easily in home or commercial dishwashers — durable finish maintains performance after repeated wash cycles. Leak performance: The twopiece Boston design has been selected and tested to form a reliable, watertight seal. It resists freezing shut and pours cleanly without dripping or spilling, so you get consistent, mess results every time. Dual functionality: Use the shaker for shaken cocktails (Margaritas, Daiquiris, Mojitos) and use the larger tin as a vessel for stirred drinks (Martini, Manhattan, Old Fashioned). Tins also nest inside each other for compact storage. Versatile for every user: Suitable for professional bartenders, home mixologists, and catering teams — handles volume service and casual entertaining equally well. Practical use scenarios Home entertaining: Shake margaritas and mojitos for a dinner party, then quickly clean the set in the dishwasher between rounds. Professional bar or catering: Rely on a durable, stainless set that withstands heavy use without seals failing or glass breaking during busy shifts. Cocktail prep and smallbatch mixing: Stir a Manhattan in the larger tin, then nest the tins to store easily on a crowded prep shelf. What you get A reliable, allstainless Boston shaker set built for durability, easy cleaning, tight sealing, and flexible use across shaken and stirred cocktails.
