Two questions.
Assuming there is a stable indoor environment. What would be the best box or container to store multiple pcgs slabs?

There are so many.

I am partial to those with inert material and a sacrificial anode (built-in or added.)

What type of box do you most use with inert material? Wood, aluminum, plastic, acid free cardboard or other? For the sacrificial anode I would guess some pure copper. I've got many copper rounds for that.
Also would a silica packet be a good idea for moisture protection? I am using the silica packets now in a wooden box.

I keep all of my slabbed gold in these. Never had any issues...even with the modern shiny stuff.
