Usage Tips:AND PRACTICAL - The window screen is made of robust material and offers reliable protection against annoying mosquitoes, wasps and other unwanted insects that can enter the house. This effectively prevents unpleasant bites and allergic reactions. ADAPTABLE - The screen is suitable for all windows with a frame width of at least 9 mm. In addition, the screen can be cut to a maximum of 150 cm x 130 cm and can be individually adapted to each window size and then attached with the supplied magnets. FASTENING - Attaching the screen is easy thanks to the magnetic attachment. The 16 magnets ensure an extra strong hold. To do this, simply attach the 16 magnetic modules to the window frame and the counterparts to the net - without drilling or screwing. FLEXIBLE - The screen allows you to continue opening and closing windows without any problems. Additionally, after the season, you can detach the mosquito net from the magnets without leaving any residue and remove them without glue residue. DECENT - The black material is breathable and semi-transparent. So, with the mosquito net, you don't have to give up the beautiful view of the outside to protect yourself and your family from annoying insects and unwanted flying animals.
