This nunchaku is made with a 28mm diameter, 1.5mm thick grooved aluminum pipe and a plated iron chain. The grooved pipe prevents the nunchaku from slipping out of your hands when swung, and it's also dent-resistant. It's lightweight, allowing for fast swinging, and durable. It also makes a great display piece. How about using it for building a healthy body, training, and exercise? Sticks: Approximately 30cm long, 2.8cm in diameter Chain: Approximately 14cm long Weight: Approximately 253g This is a one-of-a-kind, handmade item, so it has some scratches and dirt. It is not recommended for those seeking a factory-produced, flawless item without any imperfections. #NunchakuLife #Weapons #Karate #Training #MuscleTraining #Exercise
