The balls are made of a high quality, durable hard plastic material, with the Playaboule logo molded in. Because the balls are translucent the LED light can shine through making the balls flash and glow in the dark. They can be easily seen in the dark from more than 100ft away. Simply press the recessed button to turn the light on/off to activate in flash mode or press again for non flash.
We designed these balls to be as close to a solid sphere as possible. There is a small air pocket/s left inside after molding. A threaded a hole is molded in the side for the LED plug. Being as close to solid as possible, these balls are almost unbreakable.!!! You can crash the balls together without fear of damaging the balls or the LED components.
The balls have a 1 year warranty against breakage or cracking. Not covered of course is hitting something harder and than the ball is, like cement, rocks, etc, even then they usually just bounce off. The plugs have a 90 day warranty. The reason for this is that if any problems are going occur due to manufacturing/assembly, they will be evident, certainly within 90 days. Because the batteries are pre-installed to test every plug before packing, issues with the plug are rare. Long term the only issues we hear of are circuit board/battery corrosion, most often because the set is stored with the batteries left in for long periods of storage, damp with plugs not tight, foreign material, sand, water etc entering the plug enclosure because the plugs are not screwed properly creating a seal.
