Has anybody found a source for quality glow beads besides Radical Glow? I'm looking for a secondary source for glow beads that actually glow and don't just say they glow. I'm tired of buying stuff that says, "Glow" on the package but goes dim the minute I take the light off of it. Radical glow has proven to be the only "glow" product of any quality but also looking for a secondary source.
