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

Using for my 3D printer filament. The directions to recharge are printed right on the pack, so ill never lose them. Seems to be holding the box steady, great product so far.

Reusable, cheap and easy to see.

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.

Bought these for my pantry and closet. Doing the job perfectly.

These desiccant bags are perfect for keeping my filament dry. I bought a five pack though one bag is more than plenty for a small airtight container like the one I use.

These are great and reusable!!! There is a color changer that tells you when it is time to renew!! Recommend these if you live in humidity!!

Perfect size for a medium size tote.

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

The dessicants are used for a closed area that can get musty. Works very well!
