We just got back a bunch of 14" pancake tapes housed in horrible boxes. 
I have been looking everywhere on the web for decent containers for 
these (at least boxes with hubs), to no avail; the only thing I can find 
is plastic (vented) boxes for 2000' of 16mm film, which are of a similar 
diameter, but I am very wary of storing pancakes in boxes that are twice 
their width. One solution would be to find 14" reels and then storing 
those in the film boxes, but I cannot find 14" reels either.

I was wondering if anyone else has run into a similar problem recently, 
and, if so, how they solved it. Or, if anyone knows of a supplier of 
such items.
