New open box.  

3 balls

3 LED lights to insert into end of ball

3 remote controls

3 extra batteries

2 patches

I removed tabs from 2 remotes and ? of the lights to test and inflated 1 ball.  

These seem to be described as being 16”, but when I inflated, only 14” with a slow leak.

I did not check waterproofness.

Not that fantastic quality, but fun.
