Dry & Dry [7 LBS Premium Pure & Safe White Silica Gel Beads(Industry Standard 3-5 mm) Silica - Rechargeable Silica Beads, Silica Gel, Desiccant Beads

My goodness people, if you are storing Electronics in a plastic bin in a storage room, even climate controlled, protect it with some desiccant in a jar with small holes in the lid. I once lost a very expensive Sony stereo .From condensation. If your item is very expensive piece of electronics, consider buying GoVee humidity sensors which will alert you if the humidity gets too high

I am using the silica gel to dry an airtight box for 3D Printing Filament. Some 3D printing filament is hygroscopic and sucks the moisture out of the air. Using Silica Gel is a fast easy and reusable way for me to keep my filament from becoming waterlogged and sounding like bacon frying on a skillet. I Bought a pack of cotton bags for the purpose of being able to dump "spent" Beads on a baking tray and dry them in my oven. you can reuse the really nice heavy-duty bottle that comes with your beads and create a cycle of beads.Update:These are keeping my filament nice and dry, I have a 51 l gasketed storage container that all of my filament is currently sitting in right now. I have about 300 G of the silica gel in muslin cotton bags. The container started out at about 33% relative humidity, and after adding the silica gel over the course of 2 hours dropped to 10%. It has since stayed at 10% for the past few days. This silica gel is working fantastic, and the fact that you can put it in your oven and reactivate it makes it a worthwhile purchase for keeping filament dry at least. 10 out of 10, very satisfied with this product.

I am very pleased with this reasonably priced silica gel. I have been using it to keep condensation low within vacuum-sealed, frozen, fresh-cut flower bags. The beads are easy to recycle via sun-baking, or the oven method which was in the description. I will be purchasing this product if I need more of these beads in the future.

Sewed shoe absorbent bags with this as filler. Keeps shoes dry and fresh with no odor. Love it.

Works perfectly for preserving flowers.
