These solar wind chimes are gorgeous both day and night. They are beautiful on their own, or perfect for you to add your own personalized touch to them with our adhesive vinyl. You can put words on each of the 4 metal dangling tubes and a quote on the bottom wood fob. During the day they are silver and white and at night the lights come on and each of the 4 bubble tubes change colours automatically. They are solar powered so no changing of batteries. They measure approx 27" long from the hook at the top to the bottom wood fob.
