By Benson Star water sensor

At last! An exclusive water sensor for your Christmas tree! With a pretty matte black metal star that indicates when the water level is getting too low, you know exactly when to water again and the tree never has to go without water. The star is also decorative, and if you prefer to hang it in the Christmas tree, that works just as well, otherwise you hang it directly on your stand using the hook on the back. Comes in attractive recycled kraft paper packaging. Blink when the Christmas tree is thirsty! 1. Hang your star either directly in the Christmas tree, or using the hook directly on your stand. 2. Place the end with the sensor in your Christmas tree stand. 3. When the water level drops below the sensor, the star flashes.
