Optical Fun by Werkhaus are up-to-date designs of traditional optical amusements. They are handmade in Germany with high quality components and have a solid look and feel.The Optrixx is a looking eye in classic camera shapes (pre-assorted with Hassleblad, Kodak, Leica, Nikon, and Ziess Ikon). Look through and see objects reflected hundreds of times or hold over your camera lens for amazing effects (we've tried it, it really works!) Made from recycled wood fiberboard printed with four color graphics. A handy cord makes it easy for a child or adult to carry.
