*ahem* Don't listen to me. <.< I'm evil.
I have framed all three of my Bleach repro cels in just nice K-Mart (because that's what I could get to in Guam) frames.
They hung up on my wall at work for a while, but I did rotate them out.
And I do keep them from bright or direct sunlight.
But, that having been said, the repros have not faded in the least over several months.
Rilezu, in my experience, have all held up amazingly well in basic KMart frames, even with the flourescent lights. My Mirage of Blaze has been in the same cheap-o frame forever, and shows no signs of fading yet (had it two years now).
NOW the same
cannot be said for real cels!
I had my first cel framed professionally, but without any special glass (various reasons, ignorance being one of them), and in two years, major line fading has happened.
But yes, I still love it. ~_^
So basically, I guess I'm saying, if it's a repro, be nice to it. If it's a rilezu, don't worry at all.
But if it's a real cel, take good care of it, get special glass, or get a coating to go on regular glass. Whatever.
(I can get you before and after pix if you're interested.)
OH, and I found out (the hard way... always the hard way for me...) that sketches don't fade much, but the markings may! I had an Ichigo up on the wall at work in a basic frame under regular flourescents, and Ichigo was fine, but afer a month or so, the pink pen notes had seriously faded!

So beware of that too.
