Our Modern, sophisticated patented design includes several new features that solve the woes of the classic cocktail shaker and let you effortlessly create exquisite professional cocktails. Whether you are an amateur or a pro, now you can make the perfect cocktail, all the time, every time! Shaker33 revolutionary design includes a locking top that doesn't freeze itself together when it’s time to open it. The top simply locks in place, is easy to remove, and eliminates leaks and spills. Made with the highest quality materials, Shaker33 is lightweight, shatterproof, and BPA free, and made in the USA! Our ultra upgraded strainer has two sets of holes so you have options when it comes to straining your cocktails. One set of holes are larger for fast pouring and the other are smaller to provide a finer strain for muddled drinks like Mojitos. We understand that no one likes to have a freezing hand, you just want your drinks chilled! With our patented low condensation design, it makes sure your drinks are chilled and NOT your hand! Not only that, our nesting top design allows you to keep your bar clean and the strainer germ-free, eliminating a messy and sticky bar surface!
