O/T What do you put in lock boxes to keep moisture out?

Go west, young man! Ain't no moisture out here.

Average 8% humidity year round out here. Perfect for mummies and cardboard.

Bad for eyeballs, tho.

If you search Net54 for "silica" you will find a number of threads about this:

The desiccant packs you buy at the store are mostly filler - the active parts are the small blue/pink crystals. I used to work in the rain forest and used only the silica crystals (aka gel) and no filler and it worked well. At the end of each day I put electronics in a sealed dry bag with silica in a sock.

When they are pink they are ready to absorb water. When they are blue they are "full" and need to be baked in the oven to recharge/turn pink again. I was told to use a dedicated pan for this as the silica isn't something you want to ingest. For cards you might put the silica in a small tupperware with holes you poked in the lid just to make sure there is a physical barrier between it and your cards.

With all that said, I don't use any desiccants with my stuff.

I use T206 cards, really seem to soak up that moisture.

Can moisture get into the PSA and SGC holders?

Never seen that happen but I don't think they are "waterproof" but probably water resistant. Personally I keep my cards in a cool, dark dry place so not too worried about it. I have used a little silica pack before but don't think it's necessary for the way they are kept.
