All good

Bought these to put in my ammo cans to keep everything dry. So far so good. I live in Florida where humidity is high, especially during hurricane season when power goes out and everything gets damp. So, these should help keep everything dry.

The Premium Pure and Safe Silica Gel Packets are made of pure white silica gel, making them safe for use with food items and other sensitive materials. These packets are effective at absorbing moisture, making them a great choice for use with electronics, cameras, and other moisture-sensitive items. The small size of the packets makes them easy to use in tight spaces, such as inside an enclosure for a Raspberry Pi or camera. The silica gel packets are also rechargeable, making them a cost-effective and environmentally friendly option. You can heat the used packets in the microwave for a few seconds and reuse them. With 50 packets in each package, these silica gel packets can last for a long time, providing convenient and reliable moisture absorption whenever you need it.

Whenever I buy Silica packets, I always weigh them. This is (to my knowledge) the best way to insure that they are fresh. Silica gains weight as it absorbs moisture, until it reaches its saturation point at 120% of its original weight. So, 5 grams of silica gel should weigh 5 grams when it is fresh, 5.5 grams when it is half-saturated, and 6 grams when it is completely saturated (and no longer functional as a moisture absorber). These packets weighed in at between 5.4-5.6 grams. Factoring in the weight of the wrapper (.4 g), I conclude that they average 90% effectiveness out of the package (+/- 10%). Thats good enough for me, and way better than the useless packets that you can get from unscrupulous or ignorant retailers. Shop with confidence.

I only warn you not to let them get submerged as they will completely fall apart. Other than that they work great!

I purchased these for my Gill Mask. It is a silicone mask and when worn for long periods of time, moisture will gather at the base of it and pool there. I discovered these sachets and they work fabulously. I no longer have fogged up glasses or sweaty masks. They keep my mask clean and dry. I bought a big bag and just replace them every week.

Perfect for my needs and reusable!

I am using for storage of herbs I dried at home as well as seeds I am storing. They seem work well, some parsley I dried was still a little flexible after getting out of the dehydrator and after throwing one of these in the jar I noticed the leaves got crumblier and drier in a few days.

Exactly what I needed and works accordingly.
