This is the only fire ball which can be juggled without kevlar gloves. Using the filling bottle, the centre of the ball can be soaked in fuel allowing these balls to burn brightly and safely for a few minutes - just make sure you dampen the outer kevlar coil before use. Quality construction is clear as with all Fyrefli products. Comes in a set of 3 balls with filling bottle and nylon carry bag. Only suitable for adults.
