Kettles that whistle are too conventional. Not to mention, noisy too. What you need is something not just discreet, but classy too. The Flag kettle does its share of theatrics to tell you your drink has brewed. It raises a flag. Now isn’t that just one talented kettle? Who says only mailboxes are allowed to be this awesome with flags?! The Flag Kettle is the recipient of the Red Dot Award for the year 2015. Designer: Continuums Ltd.
