Here are 3 paper safes for 8x10 paper. One is a two-high unit by Unitron, another is a one-high unit by Soligor, but I'm pretty sure they're both made by the same company (both made in Israel). They nest together nicely, and both are of the kind that auto-feed the paper when you open the little front door. Sorry, there is no Cibachrome paper inside them! The other unit is just the basic kind with the hinged lid.
$20 for everything, plus $10 shipping in the US. Outside the US will be dicier, since I'm not sure I could keep the weight down to get it within First Class limits, and Priority Mail would be outrageously expensive.
