Single Plug & Play juggling ball
These hollow balls from Play, Italy have been designed to give the juggler more control over the behavior and weight of their stage balls. As empty balls, they are a little too light to juggle approx (30g) but simply fill them with sand or seeds to your desired weight and you have a customized Russian Ball. The shell of these balls are very firm and each has a slight seam. Each ball comes with a color co-ordinated silicone plug to keep the contents safe and secure. We've tried using these with water inside too, and whilst it was kept secure, it doesn't juggle quite as nicely as the Sil-X range.
