100gx5pcs Rechargeable Desiccant Packs for Storage, Reusable Dehumidifier Bags Visible Color Indicating Silica Gel Packets Moisture Absorbers for Safe Closet 3D Filaments Electronics Camera

Just got these an hour ago. Placed a few into my 3D filament storage container and the humidity dropped within 90 minutes by 3 points--see pics. Went from 19%RH to 16%RH--so it was already a dry environment--but these little bags are doing a great job!I bought these for the material for the pouch and the visible window along w/ the fact it's easy to "recharge" them. High quality materials, I feel these will last a long time. Will post updates if anything changes.Perfect size, threw a couple in the cars. No smell--will update if that changes also.

Purchased for my firearm safe and ammunition bin. Indicator works just as described. I haven't noticed any smell. Easy to use and don't have to really think about it. I visually see the indicator when I opened the safe and can microwave and toss back in.

Seems to keep the inside of my safe dry. I used 2 of them in it. I do recommend these.

I like the ease of use and the moisture that they removed, they seamed to work good. The only problem I had was using the microwave to dry them out for reuse. The cloth packs when drying would be wet on the bottom and you have to turn them over and dry more and you have to continue this process for MINUTES. You have to be careful not to over dry because the silica will turn black and then they are useless. It is hard to judge when this will happen while you are trying to dry them out, may have just been me or my process??? Either way I have 3 left and will probably not buy again. They are nice but hard to dry for reuse.

These desiccant bags are a nice size to put in cereal boxes to keep 3D filament dry. The 100g size fits a little bit better than the 120g ... but both can work. the 100g I can actually put inside the spools themselves and of course the color change is nice for indicating when it is ready to be tossed in the microwave for a couple of low power cycles.

So far so good, for my luggage and clothes that I prepack. Needed a dessicant for long term storage. Looks well sealed so the granules won’t leak or spill out.

These work as advertised and "recharge" easily

Good product and these contain a heavy 100g of desiccant. However, if the two boxes ordered only one had 5 pouches. The other had 4 pouches. Too bad. If Amazon support helps me out I will revise review
