Uranium Glass 20mm Shooter Marble

These a flippin brilliant.  1 supplied.  Yellow with either a speckled, or swirly appearance (Supplied randomly).  If multiple are purchased I will include both styles if at all possible!  These marbles glow like a nuclear reactor (probably) and even have a subtle glow in the dark effect!  Size approx 20mm, which is bigger than a regular marble.  Awesome!
