Pete......here are a few sites that sell boxes. I have purchased from them and they are all decent quality. Some are shipped flat and require glue to assemble (I used a "gluestick"). Others are shipped assembled but flattened. I'll tell you something though....they don't come cheap.

You can also buy them at Antique Electronic Supply.

But, like the man said, they don't come cheap.

If you are really ambitious, you can make your own tube boxes. I unfolded a tube box in good condition and used it as a template. I traced the outline on some scrap paperboard (actually, the inside of an empty cereal box). I have downloaded old tube carton artwork for Arcturus and RCA (world-map)boxes and I glue this to the outline. Cut out the design and fold it into a tube box. Makes a nice, colorful, nostalgic container.

You can also try veterenary (spelling?) clinics and hospitals. The medications they order for use with syringes come in crates which are perfect for peanut tubes.

You could buy boxes but they can be worth more than the tubes. Tubes store well lose in larger boxes. You could put paper between layers if you are afraid of breakage.
I use file storage boxes. Boxes from copy paper works but don't hold up as well when stacked.

:The most expensive box I saw at www.tubesandmore.com was 65 cents. I don't see how this is so expensive. The smaller ones for the peanut tubes are only about 14 cents. If you order in bulk, you can get them at an even cheaper price. Surely your tubes are worth more than 65 cents a piece. I cannot see your cartons being more expensive than your tubes.
