DX Juggling Balls are commonly considered as the benchmark for professional juggling balls.
The DX Pow³r Ball uses the same high quality grippy, smooth and durable outer shell as other DX balls. Unlike other DX balls, the Pow³r Balls are filled with weighty ball bearings. This makes them outrageously heavy considering their size - these 2.7" (68mm) balls weigh a whopping 21.2oz (600g) each.
Some people use these balls to build muscle whilst juggling. Others use them in performances when juggling different objects to keep all items the same weight. Cunning!
