This is a nunchaku with wooden octagonal grips and a metal chain. My father, who loved karate, bought and used it to train. I believe it was purchased over 20 years ago. The construction is solid. The octagonal shape makes it easy to grip, and the length of 36 cm makes it authentic. There are some scratches and stains, but it is still in good condition and can be used. - Type: Wooden nunchaku - Chain Material: Metal - Grip Shape: Octagonal Long diameter 3.0, chain part 2.0, chain length 10.5cm Thank you for looking.
