100g Rechargeable Desiccant Pack of 5 - Moisture Absorbing Bag - Desiccant Dehumidifier for Storage Bins and Totes …

easy to use, reusable, and a good value.

Purchased to put in a plastic bin with my printer filament. Perfect size and price was good. Like the aspect of being reusable

Bought one of these to try out - this one stays in my onion drawer, and picked up a couple more so I could set up a dry storage for 3D printing filament. My onions are happier (as long as I remember to recharge - the drawer gets humid fast, especially in the summer) — and my 3D printing has been going really well since I set up the dry box with the desiccant pack. Easy to spot the blue box through a semi-transparent plastic bin, so I know when I need to recharge. Just keep in mind that the pack is hot after you microwave it - just give it a few minutes to get back to room temperature before storing again.

Great quality, and they are small to put it on tool boxes, suitcase and other small places.

I used the desiccant to preserve a few cartridges which had primers until I needed to reload them. Nothing like a scientific test but Id bet it did the trick. Don

This pack is perfect for my safe. Great product design and seems very durable for the pricw

I like the ease of use and the color changing to let you know when to dry them out.

Man, what a great idea! We are constantly having issues with our attic storage stuff getting musty or moldy. We have our winter gear (we live in North Carolina), old Halloween costumes, Christmas decorations, and camping gear stored in totes. Every single one of them gets musty or damp in the summer. This little bag of magic solves all of that. I cant wait to test out the recharging feature, havent had it long enough yet. But I cant already tell its making a difference in our attic. Probably gonna buy more.

Used this in my freezer converted to fermentation chamber. Works fantastic! Always had moisture inside and now none. Highly recommend.

It probably can keep filament at equilibrium but it cant dry a wet roll. Silica gel has to be cold to absorb water while filament has to be hot to release water. At room temperature, it doesnt take any water out of the filament. You need a desiccant which absorbs at high temperature like CaCl.
