Review: Product as described and swift delivery - The items match the description and the delivery time was exceptional. Cannot verify on the product's functionality until some time passes but feel confident.
Review: Good product - They work exactly as described. Color changes from orange to green. They're reusable but one downside is the time needed to dry the silica gel: 3 hours in an oven at 250 F. I use 1 in my car and 1 in my camera bag. Instead of an oven I use an air fryer. Air fry for 15 minutes at 250 F and leave them inside the fryer for about 10-15 minutes with the air fryer turned off (while it's still hot inside). Repeat that 1x to 2x if necessary. So that's a maximum 45 minutes air frying with 10-15 minutes breaks in between. They become dark orange when completed, ready to reuse.

## Features

- 【Portable and Durable Silica Gel Aluminum Desiccant Containers】: Silica gel aluminum can is designed with convenience and durability in mind. Each canister measures 4 x 2 x 0.5 inches, providing a compact size that is easy to carry and store. The high-quality aluminum construction ensures the canister remains firm and sturdy, protecting it from dents and damage. With their independent and portable design, these small silica gel tin canisters are a convenient solution for your storage needs.
- 【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 LIGHT 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.
- 【Transparent Window & Easy Reactivation】: With the transparent window, you can easily monitor the color of the silica gel. If it turns from orange to light green, it indicates that the environmental relative humidity is above 50%. To reactivate the reusable silica gel canister desiccant dehumidifier, simply place it in the oven for 0.5 to 3 hours at 200°F to 250°F (avoid exceeding 250°F). The actual reactivation time may be shorter depending on the condition of the silica gel beads.
- 【High Absorbing Capacity and Versatility】: Our silica gel offers exceptional moisture protection for enclosed and sealed storage spaces of up to 30 cubic feet. Whether it's a safe, ammo cans, tool box, 3D printer filament storage box, weapon case, closet, or any other valuable storage container, our silica gel provides an effective solution to prevent moisture damage.
- 【Package Contents】: You will receive 5 packs of 40 gram indicating desiccant canisters. Each desiccant canister is individually packed in bags for easy storage. It is perfect for safeguarding guns, important documents, collectibles, books, jewelry, photo albums, shoes, camera lenses, expensive photography equipment, toys, leather clothing, ammunition, and photo equipment. Its versatile usage ensures the preservation and protection of a wide range of valuable items.
