Key Features

• 【Indicating Silica Gel Beads】: Wisesorb cobalt chloride-free orange indicating beads (2-4mm in size) are designed to change color within a humidity range of 20%-50%. Once saturated with moisture, the beads will complete the color change to green. It's important to note that the initial color change does not indicate full saturation. The beads will continue to absorb moisture until reaching 50%RH. We recommend periodically checking the silica gel beads to ensure their effectiveness.
• 【High Absorption Capacity】: In a sealed container, a general estimate suggests that each 40 grams of active indicating silica gel can safeguard up to 30 cubic feet of any enclosed storage space. Various containers can be utilized to facilitate the performance of the beads, such as fine mesh food straining bags, T-Sac tea filters, tea bags, drawstring organza bags, muslin bags, mason jars, or women's hosiery.
• 【Simple Reactivation Process】: Each indicating bead is vivid orange in color. If the beads transition from orange to green, it indicates that the environmental relative humidity exceeds 50%. Reactivating the reusable silica gel bead desiccant dehumidifier is easy—simply place it in the oven for 0.5 to 3 hours at 200°F to 250°F (do not exceed 250°F). Depending on the condition of the silica gel beads, they may require less time than the recommended duration. Be sure to monitor the color change of the silica gel beads.
• 【Versatile Application】: Indicating silica gel can effectively safeguard any enclosed storage space, including safes, ammo cans, ammo boxes, toolboxes, sealed 3D printer filament containers, weapon cases, closets, and more. The 2 lbs indicating silica gel offers an ideal solution for preventing moisture damage to guns, important documents, legal papers, collectibles, books, jewelry, photo albums, shoes, camera lenses, toys, leather clothing, ammunition, photo equipment, and air dryer systems.
• 【Individual Packaging & Inclusive Package】: The 2 lbs of orange-to-green indicating silica gel beads come individually stored in a plastic jar for prolonged preservation and ease of use. The package includes 3 packs of silica gel beads. The wide-mouth jar facilitates effortless pouring of the beads when needed.
