Ok, Anyone interested here is a link on the exact crystal beads that expand with moisture 20X bigger then normal when started and are great to add to your humidor. The color on their web page is just food color added they are clear when ordered. This are the beads that I have been buying in the Humi-Care HX-10 for $15 +. You can put or build the the dispenser to the size that fits your humidor. Keeps all my smokes at a 68% level. I heard some guys using Cat litter product Litter Pearls and they do not use the same glycol style beads. Anyway I thought I would pass the info along and are priced at a great price!!
