2 Gram Silica Gel Packets - Blue to Pink, Rechargeable Desiccant Packets and Dehumidifiers (Indicating, 300 Pack)

This shipment of "Pillow Paks" Blue to Pink arrived super-fast, within two days. I was glad to see that all the pillow paks were dark blue, which indicated that the were fresh, and they were packaged in two, see-through, stand-up, resealable packages. Very convenient to see the contents and retrieve paks as needed from resealable container so i didn't have to transfer the contents to another container. I love the idea that the pillow paks will change from dark blue to pink when they have absorbed their maximum moisture, so I will know when to replace them. I was very pleased with the swiftness of the shipment arrival and thoughtfully-packaged contents. I would definitely order this product from this vendor again.

I use these to protect a small collection of in-ear headphones from a slightly humid environment. They tend to last about a week inside each small container before they go pink and need to be swapped out. Once enough of them have turned pink, I throw them on a baking sheet in the oven and a couple hours later they're back to blue and good as new. For me, the original bag has worked well for storing them before use, as they've held their color as long as they stay in there.

As a follow up to my previous review, I would give these 1 star. Complete waste of money! They absorb moisture in no time, then have to be thrown away since they can't be recharged, despite the description to the contrary on Amazon. Would never buy them again :-(

I am using these for something different than most it appears, i put them in my pockets to prevent getting gauded or chafed. While i was waiting for them to arrive i was disappointed reading many reviews of them not turning color even when held over boiling water. First day i got them i put 3 in each of my front pockets and forgot about them, the next day i remembered and pulled them out and they were pink so they are obviously absorbing, and as humid as it is here right now thank goodness. All i can say is i am very happy just put some unused ones in my pockets for tomorrow and when i have 20 or so used i'll try recharging and post a review on how that went UPDATE : not sure what some in here are talking about but these packets recharged just fine, especially in my oven... 2 hours completely back to blue

I use these to keep my medications a loose powered supplements from getting clumped up. They do the job they as advertised, small enough for small containers but big enough to throw a couple in to cover the larger containers. Not really good for huge tubs of powder (like protein shake powder), but great for average sized containers.I had been using and reusing the packages that came with the various household products I have already, but needed more. I came here thinking to get the same kind of packets that I already had, and it was here I learned that they actually expire. I have no idea why I thought they didn't expire, I just needed more because I had more containers to use them in and not enough packets. Fortunately , I came across these ones that not only do the job, but let me know how they are holding up, and still allow me to "recharge them". Perfect!

This is hard to judge. The packages come with a large amount of product inside. Moisture is removed VERY rapidly in tight spaces even with a sufficient seal. They can be recharged, so it may be beneficial when using that feature over time. Not what I would want for long-term issues, but will try various applications. May add more of a review later and update.

Underwater cameras absolutely need this product, and even better that it turns pink once it has absorbed all the moisture it can. Pro tip: if you're in a humid environment, put 7 or so bags in a separate ziplock and use those first. Then put some more in the separate ziplock. That way you're not exposing your entire stash to humidity (causing them to absorb a little each time) every time you need a new bag.

These are working well in my underwater camera case, but not as quickly as I would like them too. But generally pretty good buy and do the job.
