-This is a shaker that makes it easy to generate micro-bubbles by thoroughly polishing the inside by YUKIWA, a manufacturer of Western-style tableware that Japan is proud of worldwide, to make the cocktail more mellow.
-By thoroughly polishing the inside of the shaker one by one craftsmen, it is easy to generate microbubbles in the cocktail.
-Micro-bubbles are tiny bubbles of 50 microns or less in diameter. Large bubbles quickly come to the surface and disappear, but the micro-bubbles have less buoyancy, so they stay in the liquid and make the cocktails more rounded.
