how to storage steelbook?

[SwiftDeath]

I would recommend something like these

They offer rather good general protection for your steels

Not sure if you need 200 though

But always nice to have spares

Then I would recommend a very very good carboard box

I personally keep some in a strong cardboard box and have one bottom layer than a thin layer of cardboard then a second layer of steelbooks and I find that works very well
