- 【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.

Recommended by a friend and purchased for my son living in humid north Queensland, to hopefully combat the mould challenges with items in storage.

Tried them in a wet environment and color changed as expected. Placed in oven as instructed and turned back orange. Good product.

I am using these to help keep the humidity down where I have my coin collection. Hopefully these will hold out well in the summer when the humidity can be a problem, and I can swap out the fresh ones for when I need to regenerate the one in use.

I’ll admit that I expected the orange and green colors to be more vibrant, but it makes sense that the photos’ colors are enhanced for effect. The silica gel would literally have to be glowing to look like the enhanced photos.
The attached photo, also from the product listing, is an accurate depiction of what mine looks like in a brightly lit room. Medium lighting (specifically the lighting in my closet) wasn’t enough for me to clearly tell what color it was. With the tin being the way it is, there’s not much light going in there so they do tend to look darker. Mine isn’t as dark as how some others make theirs out to be.
Kind of expensive for silica gel inside a cheap tin with holes in it, but I guess the convenience factor makes up for it since I wasn’t about to DIY it.

Used in a safe. Have had to “recharge” in the oven once so far after several months (sub-tropical climate). Overall pretty satisfied with them.

Perfect size for my small safe

I recently purchased the WiseTin Indicating Silica Gel Canisters and I’m thoroughly impressed! These canisters come with high-quality, cobalt chloride-free silica gel beads, sized perfectly between 2 to 4 mm. I found the 40 gram size ideal for my needs, and the fact that it’s non-toxic is a big plus, ensuring it doesn’t harm the items it’s protecting.
The moisture absorption performance is top notch. It keeps everything dry and free from moisture damage. What I love the most is the reusability – a quick 3-hour stint in the oven at 250°F, and they’re good as new! Plus, the color-changing beads make it super easy to know when it’s time to reactivate them.
I highly recommend WiseTin’s Silica Gel Canisters for anyone looking for an effective, reusable moisture-proof solution. They’re a small investment for the protection and longevity they offer to your valuables!

These are perfect for small and medium size gun safes. You can also use them in gear totes in areas that may be prone to moisture or subject to temperature changes.

They worked will good

The holes have been machined poorly and most don’t even penetrate the container. I was suspicious that they had not changed colour after days in a high humidity room. I took the tin apart and it has very few holes that are all the way through so it’s not going to work.

After using disposable desiccant for years in our trailer, these work just as well. We put them in the fridge freezer, and ice maker after a camping weekend. These prevent mold/mildew from forming, in the excess moisture left over when leaving the equipment turned off.

Got the larger ones to keep in the cabinet, and the 5pk of smaller ones for ammo crates and hardcases, they work as advertised, and reactivate after baking. ADVICE: reactivate them on a regular basis, they don’t take long to green in a humid climate. Definitely do not open them, you’ll never get the thing to stay closed again.

Bought these to prevent mold in the refrigerator in our trailer while not in use. It worked well to reduce moisture. The only thing is, ours arrived with pale green crystals, not orange. After use they turned a darker green. We question whether the items were somehow exposed to moisture before we received them however the packaging seemed completely sealed. I almost took it back but decided to give it a try. Glad I waited. The directions say to put them in a low oven to restore to orange which we haven’t tried yet. While camping we exposed them to direct bright sunlight for an entire day which lightened the color back to light green but not orange. We had hot weather and didn’t want to heat up the trailer by using the oven. Overall we’re pleased with the product.
