These new lighted Poi balls are brightly illuminated with an LED. The balls are constructed from a soft vinyl skin and are filled with plastic pellets which give the ball proper weight for swinging and also disperse light for a soft, even glow. The Poi Balls are connected to a finger strap with a fully adjustable braided nylon cord or stainless steel ball chain (for those wanting extra weight). Cord or ball chain connects to Poi Ball using a snap hook, allowing easy removal or change of ball. Choice of Nylon or Leather Straps - double loop nylon straps will be included unless otherwise specified - [more finger strap info here]. Each ball is powered by 3 button cell batteries. Simple operation with a small recessed switch - rotate clockwise or counterclockwise to turn on or off. Note: Each Poi Ball includes one Light Kit. Each Light Kit includes 3 batteries. Additional Light Kits are available - use for replacement, spares or to change colors. Additional batteries are available in packs of 3.
