1 Pound 2-4 mm Premium Blue Indicating Silica Gel Beads- Reusable Desiccant Beads Silica Gel Rechargeable Moisture Absorber Silica Gel Desiccant

Great value and good amount

The beads are great, they are vibrantly colored and clearly change color when water is absorbed. They're working well maintaining low (~10%) humidity for my 3d printer filament. It's a great deal for the volume shipped (maybe not delivered).The down side is the packaging. It's essentially a zip lock bag. It appears it should have been heat sealed as there is a notch to tear above the zip lock, but mine was not. Amazon shipped this with other items and the zip lock opened up in shipping. Beads were everywhere. They were coming out of the box and let's just say this was a mess. Pile on the porch, dribbling while sprinting to the kitchen sink. I poured most of them from the un opened box into a bowl. They worked their way into the packaging of other items. It wasn't fun. I have no idea how much was lost in transit.Again, the beads are good. The price is right. The packaging is risky. Roll the dice if you like. I may try again ordering these on their own which may help. Good luck!
