Features 1. The silver bird-proof windmill uses wind movement and light reflection to keep birds away. The silver bird-proof windmill can easily rotate in the breeze, and protect your garden, farm and lawn by producing a bright flash that can scare away birds. 2. The windmill is made of safe, non-toxic PET material, which will not cause harm to the environment and animals. Our bird repellent windmill does not scare and harm birds, but humanely scares them away by reflecting visible light. 3. Garden decoration: Silver bird-proof windmills are enough to attract the attention of birds in the distance. They rotate in the wind and reflect the sun. They are very beautiful. They are also an elegant complement to your garden. 4. Wide range of uses: Silver bird-proof windmills are widely used in orchards, gardens, barns, and trees. Prevent your garden, windows, orchards, barns, crops, boats or cars from being harmed by birds, and make your house, yard, lawn, pond or other more beautiful. Windmills can also be used as fun toys for children. Specifications: Material: PET Size:48 x 18cm,52x 24.5cm Color:Silver Package Included: 10x Bird Repellent
