Rinka's cel bags? I haven't noticed any 
difference in cel condition, and the bags 
themselves seem to stay fairly clear. I like the 
fact they don't have sticky strips and are a 
little thicker.

I have to admit though, I assumed they were acid 
free. I can only read bits and pieces of the 
Japanese, so I'll ask my roommate when she gets 
back from vacation.

Just my experience--so far no complaints.
