The mouth-blown glass drop is filled with water. Suspended on a thread, the light is reflected in it. The more drops are hung, the greater the effect. Did you know that the drop filled with water can be used as a fly repellent? Hang lots of drops on the tree in the garden. Due to the magnifying effect of the water and the movement, it deters flies. A sustainable fly repellent and an atmospheric eye-catcher in every garden.
