Almost lifelike, OWI's aluminum insect building kit features a praying mantis insect that you assemble from metal and bendable aluminum parts. The average size of the scientifically named "stagmomantis carolina" is 3 to 4 inches in length. Mega Mantis is twice this size, henceforth, its name emerged. It is quite a remarkable carnivorous insect. Its spiny-like fore legs are used to catch and hold prey. OWI's bendable buddy is a little more user friendly. You can hold it, bend it, and even move its legs, wings, head and fore legs. The kit contains 25 hard and soft pre-punched aluminum parts, 7 screws, 7 nuts, 4 metal springs, and even assembly tools are included. No Batteries Required.
