These Wisesorb silica gel canisters work exactly as advertised. I use them in my gun safe and tool cabinets, and they effectively absorb moisture without any mess. The color change from orange to green makes it easy to know when it’s time to recharge. I appreciate that they’re reusable—just pop them in the oven and they’re ready to go again. Great value for long-term moisture protection.Q&A Section:Q: How do you know when they need to be recharged?A: The beads turn from orange to green to signal it's time to recharge.Q: Can these be reused?A: Yes, they are fully reusable—just bake them at low heat to dry out the moisture.Q: Are they safe to use in gun safes and closets?A: Absolutely—odorless, leak-free, and compact enough for tight spaces.Q: How long do they last before needing recharge?A: It depends on humidity, but generally they last 2–4 weeks before needing to be recharged.

I bought the Wisesorb 40 Gram Silica Gel Canisters to use in my Kobra S1 ACE Pro filament dryer, and they’ve worked perfectly. They keep the humidity under 39% most of the time, which makes a huge difference in print quality.What I love:Reusable: Just dry them out and they’re good to go again.Practical for 3D printing: You can even 3D print a holder to attach them to the roof of the ACE Pro, which makes them super convenient.Great value: A pack of five lasts a long time and gives plenty of coverage.These are awesome little canisters and do exactly what they’re supposed to. If you’re looking for a simple way to manage humidity in a filament dryer, I highly recommend them!

These are a great product and I really like that you can recharge them in a microwave. I have others you have to do in an oven and takes much longer to recharge.

When it comes to my firearms and ammunition storage, I'm a little bit of a fanatic when it comes to quality. I received these and use them in all of my firearm and ammunition hard cases. I've also used them in file folder plastic containers where I store paperwork for my conceal carry classes I teach. I've ordered these multiple times. I've never had to recharge on (and hope I'll never have to). Because I haven't hard to recharge, or seen any water damage in any of the cases, I can't attest to their longevity. That's the ONLY reason I'm giving this four stars instead of five. I don't like when people post a five star review for a product they haven't yet used it its entirety. Those aren’t helpful in my opinion. With that said, I have a sense of comfort that these will protect everything within the cases in which I put them, which is why I've purchased these multiple times.

These things work like a charm. They're my go to for my ammo boxes, however, I use them in my closets as well. Extremely easy to dry out, a great time and money saver.

Just got these an hour ago. Placed a few into my 3D filament storage container and the humidity dropped within 90 minutes by 3 points--see pics. Went from 19%RH to 16%RH--so it was already a dry environment--but these little bags are doing a great job!I bought these for the material for the pouch and the visible window along w/ the fact it's easy to "recharge" them. High quality materials, I feel these will last a long time. Will post updates if anything changes.Perfect size, threw a couple in the cars. No smell--will update if that changes also.

I like the ease of use and the moisture that they removed, they seamed to work good. The only problem I had was using the microwave to dry them out for reuse. The cloth packs when drying would be wet on the bottom and you have to turn them over and dry more and you have to continue this process for MINUTES. You have to be careful not to over dry because the silica will turn black and then they are useless. It is hard to judge when this will happen while you are trying to dry them out, may have just been me or my process??? Either way I have 3 left and will probably not buy again. They are nice but hard to dry for reuse.

Works very well very durable and last awhile in my safe and ammo crates before needing to be recharged
