New MacKenzie-Childs Whistling Tea Kettle At Glassworks! Whistling while it works, the Courtly Check Enamel Whistling Tea Kettle lets you know when your water is ready. Hand-painted with signature black and white checks over a heavy-gauge steel underbody, it serves to beautify your stovetop even when it’s not in use. Also can be placed on display elsewhere, filled with fresh-cut flowers or greens. A perfect gift for seasoned collectors, or a welcome introduction for a friend.
