I use black bin liners cos they don't let the 
light in so no line fading due to light!  Also 
when a cel robber comes along they do not think 
to look through them as they look like garbage & 
they think that no one could possibly be so cheap 
as to store their cels in them.. lol

On the negative side though, they might get 
thrown out as trash by mistake...

lmao
