CLEVAST Silica Gel Packets Desiccant Packs for Storage 10 Gram 30 Packets, Silica Packets for Moisture Control, Food Grade Safe, Rechargeable Moisture Absorbers Gun Safe Dehumidifier for Jewelry

Great for bulk spices

I actually cut these packs open and put them in some custom 3D printed silica gel holders that go inside the spools for my Bambu Labs AMS. They work out pretty well as I get 3-4 packets in each one. When they get some moisture, I put them on the warm setting in the stove in a glass/ceramic baking dish for about 1-2 hours and then let the oven cool naturally and then fill the holders back up and I am good for some time.

These work well to keep to keep cereal and other items dry and fresh, and reduce the time to become stale. It's useful that some of the beads change color as they absorb humidity so that you can know when to "recharge" them in the oven. It makes a noticeable difference in the cereal jar. I was surprised how quickly the color changed (less than two weeks in a humid area), but at least it works!

So I like to get these to put in storage totes that we keep on our screened-in patio. Humidity can totally mess up your stuff and we live in Arkansas so it's frequently humid. I throw a few of these in each tote. These are on the smaller side capacity wise so mine were "full" in a matter of days so I'll have to recharge them frequently, but it's easy to tell at least since they change color when full. If you live in a humid environment I'd recommend getting larger ones unless you are ok with recharging them often.

In the box, you'll find a plastic bag containing all of the desiccant packs. The front of the packaging shows the various "recharge" methods including a microwave, oven, and sunlight. The desiccant packs themselves explain when to reactivate and feel sturdy themselves, especially compared to the packs you get with your electronics. All of the beads start orange, as seen through the packaging, and will turn green as they absorb moisture. This is not only useful for knowing when to replace the packet, but also an indicator of possible moisture intrusion. It's a handy feature. The efficacy isn't something that can be determined within a week, so I will update this review if there are any issues down the road! I plan on using them to protect my 3D printer filament and other sensitive equipment.

GREAT! I have some in my protein powder since the container doesn't close fully and it was getting clumpy. 4 of these made it nice and fluffy again!!! I rinsed em off and chucked em in my lil oven set to dehydrate at like 100F for like 5 hours and they were good as new. They absorb a lot of moisture soooo fast in that container I put 6 in, that helped so I don't need to dry em every 4 days. Anyway I realllly like these and one gets put in anything that can't seal very well now. Rinsing and reusing hasn't given me mold or smelly packets too. I just dry them right away

I ordered these packets for my homemade beef jerky and they work great. They are a larger size which is perfect for my gallon storage bags. They controlled the humidity and helps to keep food longer. Absolutely worth the cost.

It’s hard to write an immediate review of silica gel, so I plan to update this after a month or two of letting some packets soak up ambient moisture.The paper seems high quality and porous enough for the purpose. The beads themselves are fairly large, and the packets themselves were larger than I anticipated. (I ordered them thinking I’d use them in IEM cases, but at best they’ll fit with my over-ear headphones. It’s okay! That one’s on me, and there’s plenty of ways to use them.)Packets arrived tightly sealed in a resealable bag, inside of a sturdy cardboard box for ease of storage. I’m not worried about ambient air affecting packets not in use, and the instructions for re-desiccating the packets are pretty straightforward when it’s time.(The reviewer who was upset over the beads arriving orange may have been a bit confused — orange is the starting color and green is what they turn when they’ve absorbed all the moisture they can.)
