I bought this for Kittessensu 3-Part Boston Shaker set for $20, and after doing some research, I found that a Boston shaker is considered one of the best types of cocktail shakers. This became my very first one, and I couldn't be happier with it.
I've used it many times and have shaken it vigorously without a single leak. The seal is excellent, yet it's still easy to separate after shaking.
I also love that it comes with the essentials: a Hawthorne strainer and a double jigger. It includes exactly what you need without a bunch of unnecessary accessories that just take up storage space.
We live in a 950-square-foot home with a small kitchen, so I appreciate that all three pieces store neatly together. Great quality, practical design, and an excellent value. Highly recommended!
