I purchased this, but it didn't fit my window, so I'm selling it. It attaches with Velcro. The opening in the center uses magnets. → The magnets are a bit thick. Please check the photos. ◉ Size: 90cm x 190cm There are instructions in English for installation. ※ Please note that this is a foreign product, so there may be slight variations or imperfections in the stitching. ※ It will be folded for shipping, so there may be creases upon arrival.
