I work very close to Canal street, the land of 1,000 industrial plastics suppliers (oh, alright, three). These shops carry a dizzying array of smallish, inexpensive boxes in a variety of sizes and colors. Almost all the colors are transparent (save the black and white).I don't believe any are more than $5.00 and most are considerably less. The problem is that they tend to be a little on the brittle side and may not do too well on transatlantic/pacific voyages.
If interested, I could certainly get a variety of samples to send to whoever ends up spearheading this project. M
