Transparent, breathable mosquito net with small holes, made of 100% polyester. Open the window and enjoy the fresh air. Protect your cat and other small pets from falls and escapes. It also prevents insects from entering when the window is open. High visibility and ventilation: the mesh window screen maintains good air circulation without blocking your view, allowing you to feel the warmth of the sun, enjoy the view outside your window, the cool breeze and fresh air without mosquitoes. Keeps insects out: The extremely durable material and small holes (less than 1 mm in diameter) protect you and your family from all types of insect bites. Mosquito nets are the most effective and healthy way to keep insects away. Easy to install, no drilling required: the window screens are easy to cut with standard cutting tools and fit most bedroom windows and skylights. They are installed quickly and easily thanks to the sturdy Velcro straps (included), which can be easily attached to or removed from the window.
