The Ravensburger 4S Vision Wild Cats construction puzzle combines three-dimensional puzzle fun with fascinating optical effects. Made from 37 sturdy cardboard pieces, a 3D figure is created that reveals a different wildcat motif depending on the viewing angle. As the finished model is turned, a leopard, a lion, a black panther, and a tiger become visible in succession. The assembly is achieved through the innovative plug-in principle entirely without glue. Included instructions assist in putting together the decorative display model, which measures approximately 19 x 19 x 12 centimeters when completed.
