• High quality: The REDTRON window screen is made of polyester, which is more durable and reusable. The self-adhesive tapes can be easily removed without leaving traces and do not damage the windows. The REDTRON mushroom hook design has a better grip to prevent the mesh from falling off. • No drilling required: Just peel off the backing paper and stick the adhesive tape on the clean window frame, then place the window screen mesh, and trim the edges, completing the installation. Open and close windows smoothly. • Keep insects away: The ultra-dense window mesh (hole diameter <1.3 mm) effectively keeps insects, mosquitoes, and flies away, protecting your children from various mosquito bites, allowing them to have a good night's sleep. • High visibility and ventilation: Window screens maintain good air circulation without affecting vision, allowing you to feel the warm sun, appreciate the scenery outside the window, let the cool breeze blow, and enjoy fresh air without mosquitoes. • Wide applications: The window screen mesh is applicable to many different types of windows, such as wooden windows, steel windows, sliding windows, cabinet windows, various specially shaped windows, etc. Maximum size 1.3*1.5m can be cut into any shape and size to fit your window.
