Hi, el wacho. Directly from factory.
At photo seminar I meet one guy who was taking pictures with LF (Here in Lithuanian only few people are using LF). We started talking about photo materials... He reported: that different sets wich he odered from ebay vary in quality a lot (the same box but different sheets from differt sellers on ebay). So he manage to find contact in chine and odered directly a huge bunch of film. I get from him few boxes for tests
I think what is worth to oder direcly from factory. Of course you have to oder a lot of stuff. By the way I found on their site when reading on photo papers that they accept individual oders.
