5 Packs 40g Indicating Silica Gel Dehumidifier Desiccant Tin Canister, Wisetin Orange to Green Color Changing, SG-40 No Cobalt (II) Chloride-Reusable (Pack of 5)

The items match the description and the delivery time was exceptional. Cannot verify on the product's functionality until some time passes but feel confident.

They work exactly as described. Color changes from orange to green. They're reusable but one downside is the time needed to dry the silica gel: 3 hours in an oven at 250 F. I use 1 in my car and 1 in my camera bag. Instead of an oven I use an air fryer. Air fry for 15 minutes at 250 F and leave them inside the fryer for about 10-15 minutes with the air fryer turned off (while it's still hot inside). Repeat that 1x to 2x if necessary. So that's a maximum 45 minutes air frying with 10-15 minutes breaks in between. They become dark orange when completed, ready to reuse.

Good product. Last a long time between “recharges”. Very pleased with them.

It’s the second set I purchased! Works well with no complaints! Bang for the bucks !

Recommended by a friend and purchased for my son living in humid north Queensland, to hopefully combat the mould challenges with items in storage.
