Warning about the xray bags. I used to use them and then I went across Canada only to come home and develop all the film from my trip which was ruined by xray fog. I put 10 4x5 film holders, 20 rolls of 120 film and 20 rolls of 35mm film in two lead bags in my under carriage. What likely happened is that the security officer (when looking through the xray scan of my bag) said, "what's this in the bag? I can't see through it. Might as well crank up the juice until we can penetrate this lead bag" and subsequently ruined almost all my film. If you're asking this question because you are traveling to a country that has film, buy it there and forget the hassle. It will cost less in the long run if your film gets destroyed. If you're asking just for a case that holds 10 rolls, I've seen some interesting things on that auction site.
