Ditto. Although if you're asking how to store your glass rods to take to and fro, I have been using a plastic tube that I bought at the local gaming/comic book store. It's intended to hold a play mat for gaming, and is about 24 inches long.
For Christmas, I got a Plano 3700 tackle case (made for fishing). It's basically a large nylon back with side and front pockets and an open interior. There are plastic divided cases that can be purchased separately (it comes with 2). I bought a third at Wal-Mart, because the two that came with it had a fixed divider in one of the rows. With the one I bought (a different brand with the same measurements), there are 4 long rows, 14" each. I can divide my glass up into clear, opaque, translucent, and black/white, and it all fits in one container, though I have to put some of my stringers in diagonally.
