wisedry 2 x 500 Gram [2.2 lbs] Rechargeable Silica Gel Car Dehumidifier, Microwave Fast Reactivated Desiccant Packets Large for Safes Closet Basement Garage Storage Moisture Absorber Bag Reusable

Use for 3D filament storage container (with seal)

These allowed moisture to accumulate in my airtight containers that are used for pet food storage. They did not work as advertised and ruined some fairly expensive dog food. I would recommend not purchasing these.

After just about all it’s five minutes. Fist time trying although received about 6 weeks ago because we were not ready to used them. So saved for when we were ready and would like a replacement or refund. It’s a shame we didn’t open and try before the return window. What a freaking mistake. Don’t make it, open and try them right away.

Put this in the gun safe

Read the directions package came apart in microwave

I use these for my 3D printer filament dry box and I went to reset one of them by microwaving and I thought oh it steams so maybe putting it on a towel will help I was so wrong...it got so hot that it melted and burned the towel and spilled the silica all over my kitchen, I was finding beads for weeks! All in all, the packs work as intended, you just have to be careful when microwaving and either put them directly on the glass turntable or on a glass/ceramic microwave safe plate.

Would recommend this product to anyone. The pack last longer than expected and really do a great job!

If you live in a humid environment, you need these substantial desiccant packs for lock boxes and safes. When they weigh 23 oz (650g) revitalize them in the oven per included directions. Stop possible mold, mildew rust or corrosion by using these desiccant packs.

These are HORRIBLE and DANGEROUS!!! I received mine yesterday, followed the instructions, and as it was in my microwave, next thing I know there was a terrible smell and my microwave was ON FIRE!!!!!! Now I have no microwave, and there are silica beads EVERYWHERE throughout my kitchen!! ARE YOU GOING TO REPLACE MY MICROWAVE???

Good for small places and if needed add both the package. It keeps inside of my small car dry while parked in a humid place. I can see difference before and after, we need to know its limitation and as expected.
