6LBS Silica Gel Desiccant Beads, Premium Orange Indicating Reusable Desiccant Bulk, Industry 3-5 mm Silica Beads Dehumidifier for 3D Filament, Electronic Devices, Camera, Jewelry, Safe (10PCS Bags)

High Absorption Capacity: silica gel beads are safe, cobalt chloride-free, and provide outstanding moisture absorption. They can absorb up to 35% of their own weight, effectively pulling moisture from enclosed storage spaces to protect items from damage.
Color Indication: The orange silica gel shifts to green when 50-60% saturated with moisture. The initial color change does not signal full saturation; the desiccant keeps absorbing moisture until reaching 50-60% RH and then turns dark green.
Rechargeable: These reusable desiccant beads can be reactivated by placing them in an oven for 0.5 to 2 hours at 200 to 250°F, or in a microwave for 7-10 minutes at 700W, heating until all beads become bright orange. Depending on the state of the silica beads, it may take less time than the recommended duration; check the beads' color periodically.
Package & Warm Hint: The package contains 10 organza bags and 6 lbs of rechargeable desiccants, sealed in an airtight barrel for long-term preservation and protection. The bead size is the industry standard of 3-5 mm and is not suitable for drying flowers.
Wide Application: Color-changing desiccant can be broadly used in daily life. Use it to effectively prevent moisture damage to 3D printer filament, electronic devices, cameras, documents, jewelry, gun safes, clothes, and many other valuables
