"Dark bags"

[Greg Y]

I agree with John. I would not send films thinly packaged. Several years ago, I received a CD in a flat cardboard mailer. The CD itself was also in a cardboard case. The postage stamp cancelled mark went right through the packaging onto the CD.

I need to get the bags first, but I plan to enclose the bags in a 2nd, smaller cardboard envelope. I'll report back in a month or so after I've tried this. But, The Darkroom said they return "bags or boxes," so others must be doing this... We'll see.
