I myself found that storing media in cases like DVD cases help in preserving them and prolonging their life. An experience in a very strong typhoon, where waters entered our house since our neighborhood become flooded, showed how useful CD wallets are in times of disasters and calamities. Though my collections were gotten wet, further damages were prevented since they were stored in wallets. I am happy that months before that thing happened, I was able to buy bulk cd wallets and have my collections stored using them.

CD wallets are cheap, and using them for your media collection is a good investment.
