Packaged figure preservation

[kittychloe]

Long time without word sorry just been poor and uncollective.

For the question though, how do I stop glue of figure packaging from drying out?

I have some of the sonic anniversary figures that I had hoped to keep sealed, I was doing the same with skylanders but wend and opened them all, the reason for this though is that they fell open, the glue dried out on all the sonic figures and 50% of the skylanders so the backing just fell off, it made me a little fed up with these types of packages as the sonic figures were on hooks and just fell off the backing

Any help?
