Was in Office Depot today and found an acrylic presentation cube.
This comes in 3", 4", 5" cubes and are clear lexan. Also a desk pen and pencil container that is roughly 2" sguare and tall which would accomodate some single figure displays. While probobly not suitable for bigger builds and figures, they certainly have a good use for some of the smaller stuff and some figures.
Check it out. They run about $2 to $5 each.
