Back when I was a kid my Mum bought for me some Star Wars Power Of The Force 2 toys, this was my first time collecting toys and not playing with them. I kept them MOSC in the hopes that one day they would be worth lots of cash like the original Star Wars toys. I recently got them out and I noticed all the cards had warped, gotten bumped and dinged and the bubbles have all gone yellow. Unlike my childhood SW collection which is worthless just because it's POTF2 my small number of Transformers that I've kept MISB/MISC in my collection are going up in resale value quite nicely. But after inspecting my SW toys and seeing how the packaging degraded despite been kept away from the sun and in cool dry environment I'm wondering short of AFAing them how to keep my Transformers boxes/cards from suffering the same fate?
