PaperMonster (USA) , A1one (Tehran), and Cabiao (Buenos Aires) have collaborated with Choke Urban Creation (Germany) on a set of artist designed umbrellas. Each umbrella comes in an artist designed box and features a one button auto-open/close feature with an aluminum shaft and fiberglass ribs. These umbrellas are unlike anything you will see outdoors and truly make a powerful and beautiful statement. Great product!
