Finally found this thread; have been reading about interslice and their generic kits; have been looking on ebay for one.

I had been thinking about getting a kit; I have an old Olympus Trip 35 that takes so little foam it is a joke; but I have some older medium format gear and some 35mm that might need re-sealing.

Oh well - off to the local craft supply store! Too bad about the ebay shills- I'm sorry to hear that people like that continue to exist.
