Two PROGRESS dancing glasses that dance slowly on the table, bringing out the playfulness of adults. By rotating the glass, the wine comes into contact with the air, allowing oxidation to progress, which enhances the flavor and aroma. The swirling effect makes your usual wine even more delicious. Also, it's perfect for drinks with ice. Tumblers that rotate as if they are dancing. They slowly melt the ice, keeping your drink at the perfect temperature. Great for wine, other alcoholic beverages, and drinks! [Size] Approximately 6.5cm in diameter Approximately 9cm in height [Capacity] 270ml If you have any questions, please feel free to ask.
