Key Features

• 【Indicating Silica Gel 】: Wisesorb blue indicating silica gel (2-4mm in size) are designed to change color within a humidity range of 20%-50%. Once saturated with moisture, the desiccant will complete the color change to pink. It's important to note that the initial color change does not indicate full saturation. The desiccant will continue to absorb moisture until reaching 50%RH. We recommend periodically checking the silica gel desiccant to ensure their effectiveness.
• 【Great Absorbing Capacity】: When used in an air-tight sealed container, our indicating silica gel has a general estimate of protecting up to 30 cubic ft of enclosed storage space for every 40 grams of active gel. You can easily use various containers such as T-Sac tea filters, tea bags, organza bags, muslin bags, mason jars, or women's hosiery to hold the beads and allow them to effectively perform their job.
• 【Easy to Reactivate】: Indicating desiccant are 2-4mm in size and have a vibrant blue color. Simply check the color of the indicating silica gel desiccant to see if they have changed from blue to pink. Once they turn pink, you can easily reactivate them by placing them in the oven for 0.5 to 3 hours at 200°F--250°F (not over 250°F). Actual reactivation time may be shorter depending on the condition of the silica gel desiccant. Remember to check the color of the silica gel desiccant for proper reactivation.
• 【Versatile Application】: Indicating silica gel is widely used to protect various enclosed storage spaces including safes, ammo cans, toolboxes, 3D printer filament storage boxes, weapon cases, closets, and more. With 2lbs of indicating silica gel, you can effectively prevent moisture damage to guns, important documents, collectibles, books, jewelry, photo albums, shoes, camera lenses, toys, leather clothing, ammunition, photo equipment, and air dryer systems.
• 【Individual Packaging & Package Contents】: Wisesorb 2LBS of blue-to-pink indicating silica gel desiccant are carefully packaged in a plastic jar to ensure long-term preservation and protection. The package includes 2 packs of silica gel desiccant. The wide-mouth jar allows for easy pouring and refilling of the desiccant.
