It seems you can not find it without the blue crystals. I've got enough to last another spring/summer but will be on the look out for more.
I use KL to de-humidify as it works 10x better than beads for this. If you are using them for a desktop or small cooler just by beads. If for a large (100+ qt) cooler or small-mid size cabinet humidor get a Cigar Oasis or Hydra. Big Cabinets get the Habitat, Aucmonitor (sp), or Set N Forget.
