Type A Silica Gel: Wisesorb 7.5 lb Type A silica gel utilizes premium quality raw material: silicon silica gel. Its excellent thermal and chemical stability allows for strong moisture absorption. At 77℉/25°C and RH50%, it can absorb more than 22% of its weight in water vapor; at RH90%, more than 34%. Each granule is 2-4mm in size.

Safe to Use: Wisesorb Type A silica gel beads are non-toxic and cobalt chloride-free, making them safe for use around food, pharmaceuticals, and sensitive equipment.

How to Reactivate: Beads can be reactivated by placing them in an oven for 3 hours at 265℉ (130°C). Depending on the condition of the beads, they may require less time. Check the beads periodically. The beads can be reactivated indefinitely, providing long-term protection.

Easy-to-Pour Container: Our easy-pour container offers both capacity and control. The multi-pound volume holds a generous amount of desiccant beads that is easy to carry and pour thanks to a unique handle design. The dual-handle design accommodates multiple hand positions for better maneuverability and control.

Bulk Beads Weight: 7.5 LBS. Bead size: 2-4mm.

How to Use: Place silica gel beads into an enclosed storage space and allow them to absorb moisture until they need to be replaced. Suitable for protecting guns, ammo, jewelry, documents, camera lenses, clothes, cosmetics, books, 3D printer filament, and more.

What kind of container to put the beads into so they can do their job?

You can use any of these and will find them working well: fine mesh food straining bag, mesh bag, T-Sac tea filters, tea bags, drawstring organza bag, muslin bag, mason jar, dryer containers, knee-high nylon stockings, clear plastic storage bin, mesh laundry bags, or women's hosiery. Even make your own bags and size them to the specific use.

Good uniform product

Good uniform product. Well packed and does what it should.

Easy to use!!

Got to preserve flowers and other items. Can use manual times. Easy to use.

Clean packaging and easy dispense into organza sachets

I use this to keep our dog kibble, cat kibble super clean, dry, and fresh for all our animals. I also use this for my DIY powder food and whatever else I can think of. The way you use this without a hygrometer is to use a kitchen gram scale and measure the weight of the beads + sachet before and after and replace it when you see a 20-30% increase in weight. Also microwave + toaster oven at 200 deg F for 15 minutes (low temp) will do amazing work on recharging the beads. Considering using a skillet next time. Got these for similar reasons as other users - no indicating color means its safe. Orange indicator is methyl violet which you can wikipedia and see that its really quite unsafe, although it is silica bound. This is really clean silica gel and a great product. Can see myself using this same 7.5lb jug for more than a year with reheating.

Non-toxic option for 3D printing filament than color-indicating dye (cobalt chloride/methyl violet)

Got this because it doesn't have any color-indicating dyes like cobalt chloride (dry blue to pink wet) or methyl violet (dry orange to green wet). While both are toxic, they're technically safe to use in the sealed packets, but in raw bead form, the constant grinding between beads causes them to create dust, essentially making a dust cloud of cobalt chloride or methyl violet everytime you use it. And in that case, it becomes a health hazard.PROSValueSecure containerNo health risks from cobalt chloride/methyl violet dust cloudsCONSNo color indication so you'll need a hygrometer to know the humidity level
