Handmade, one of a kind decor for a window in your home. Octopus is made with laser cut birch, resin, mica powders, glue, and brass chain. Measures approximately 12 3/4" at widest point, 8" at tallest point, and 3/8" thick. Piece comes with a hooked thumb tack, but is too heavy for hanging with a suction cup. I have been told by customers that Command hooks also work well on metal framed windows, or in places where thumb tacks are not allowed.
