Thanks for your reply.  :)

I am thinking this summer I will get a few new 
cel bag packages and change all the bags again... 
I keep a close eye on my cels for signs of 
fading, and so far not much has happened.  

It's just that I'm starting to get a larger 
collection than I planned on and I don't want to 
see any of my cels start to "decay".  That's why 
I'm becoming more concerned about their cel 
bags.  :/

Take care!
Kristina
