Today I spoke to a dealer, he sends me 20+ IXMOOs at 10 Euros each. I also have 2 FILCAs in their original aluminium containers. I think I do not need 20 IXMOOs, and I don't need FILCAs at all. So, if you want them... however, shipping fees could be a problem again.

I have no idea whether Orwo has equipment to package 135/36ex cassettes, but there are companies that offer packaging films as a service. In the last months I used a lot of Orwo films, and I find rolling my own films from bulk rolls is really simple. The next roll will be a 400' size, that is much cheaper per 36ex film. The other brand that offers bulk film at reasonable prices is Efke. The Efke 50 is a good film, I like the look. But what I would really like to get is Tmax 400 - but bulk is more expensive than ready-made cartridges...
