Handmade, one-of-a-kind decor for a window in your home. Praying mantis is made with laser cut birch, resin, mica powders, glue, and brass chain. Measures approximately 11 1/4" at widest point, 8 1/2" at tallest point, and 3/8" thick. Piece comes with a heavy duty suction cup and a hooked thumb tack. I have been told by customers that Command hooks also work well on metal framed windows.
