Pros & Highlights

Ultimate Silica Gel Tin Canister for Dry Storage

Dimensions & Durability

Each tin canister measures 4 inches x 2 inches x 0.6 inches and is constructed from high-quality aluminum to provide a firm, sturdy protection against dents. Its compact size makes it perfect for both use and storage.

Easy Humidity Monitoring

The changing color of orange indicating beads—from orange to green—indicates moisture levels. This helps you monitor environmental relative humidity between 20%-50%. The beads will continue to absorb moisture until they reach 50% relative humidity (RH).

Transparent Window & Reactivation

The transparent window allows you to easily check the color of the silica gel. When it turns from orange to light green, it indicates that the relative humidity is above 50%. For reactivation, place the desiccant canister in the oven at 200°F to 250°F (avoid exceeding 250°F) for 0.5 to 3 hours. This helps maintain an optimal humidity level.

This silica gel canister effectively protects up to 30 cubic feet of any enclosed storage space like safes, ammo cans, tool boxes, 3D printer filament storage boxes, weapon cases, closets, and more. It keeps moisture away from valuable items such as guns, important papers, collectibles, books, jewelry, photo albums, shoes, camera lenses, photography equipment, toys, leather clothing, and ammunition, ensuring they remain in pristine condition.
