I just thought I would pass this on as I have gotten away from beads in my coolerdors because of the mess they leave as I would search through them looking for a specific box of cigars to move to my Aristocrat. I went back to the 4oz gel jars about 2-3 years ago and they've performed admirably keeping them at a consistent 68-70%. To my point...you know how the gel gets brown & funky after a while? I would replace them when they would and buy new ones for about $10 to $12 each. I would keep the old ones, throw out the gel, disinfect them, and then use them for beads. But when I bailed on the beads, I had a few empty ones available. While looking for some new 4oz jars...I stumbled across these on eBay. It's a packet of the water crystals in their dry form. Just one ounce of them fits perfectly in the empty 4oz jar once you add distilled water...and they're only $6 for the bag with free shipping. Works for me in applications where there is a lot of action and movement where beads don't work as well.
