Hollinger Corporation sells white unbuffered corrogated fiberboard
record storage boxes (Item 10760) at $4.20 per box for 25, $3.68 per box
for 50. They are 15"x12.5"x10", 7.5 pH.
You can special order coroplast boxes, same size, for about $8.00 for a
batch of 25. They have certain advantages over fiberboard, but they are
a pain in the butt to assemble.
The prices come out of Hollinger's 2000 catalogue and, of course, are
subject to change. Their number: 800.634.0491.
