Dessicant packs are free. They come packed in the box with most electronics. The bigger the electronics, the bigger the pack. They look like little pillows and are most always marked Do Not Eat (like you would) I just toss em on the floor of my safe. Stays like the Sahara in there, no rust problems. My safe is in a damp basement, I live in a rain forest. I pull the packs out every few months and bake them in the oven on low for a few hours, that drives out the moisture and regenerates the dessicant.
