The double-layer structure ensures that the external surface temperature does not drop significantly due to heat conduction during stirring. This design slows the melting of ice, reducing excess dilution and preserving the intended balance and proportions of the cocktail.

The hollow double-layer construction enhances insulation, preventing the surface from becoming overly cold and minimizing condensation, making it more convenient and comfortable to use.

The rounded base, where the back of the bar spoon contacts during stirring, reduces metallic noise, ensuring a smoother and quieter stirring process.

The interior features a two-step curved design with two distinct markings, allowing it to function as a measuring cup for approximately 260ml and 400ml.

With a full capacity of 500ml, this mixing cup is compatible with most common strainers, such as the Hawthorne strainer.
