Rounded bottomed glasses were originally designed for use on ships to counteract the rocking motion on the high seas, but you dont need to set sail to use these rockers. Watch your tipple swirling inside the glass and breathe in the aroma; Cup the glass in your hand for warming brandy, cognac and even red wine. Each glass is approximately 9cm tall x 7.5cm in diameter. Packed in a strong Vinology gift box. Capacity 300ml. 2 whisky glasses. Dishwasher safe.
