Outotsu
Outotsu means unevenness in Japanese. Stacking is now possible with the concave part of the glass and the convex part of the coaster. The coaster absorbs water droplets that form on the glass. It also has excellent deodorizing and antibacterial properties. The protrusions on the bottom of the glass create convection when you pour a drink into it, drawing in air that enhances the aroma and balances the flavor of the drink. There is no need to mix with a stirrer, and the beer will foam better. Another convenient feature is that both can be stacked for storage.
