These fun, rounded bottomed glasses were originally designed for use on ships to counteract the rocking motion on the high seas, but you don"t need to set sail to use these rockers. Watch your tipple swirling inside the glass and breathe in the aroma! For a party game rock the glasses from side to side or spin them (gently!) and try not to spill a drop! Or 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 smart gift box - 2 glassses per pack.
