The Viewtainer is an inexpensive, flexible plastic tube with a rubbery cap at both ends. Originally, they were intended to hold small parts (screws, nuts, bolts, etc.). On one end the rubber cap has a slash in it, so when you squeeze the tube, you can dump the parts out. Although these Viewtainers may work well for storing parts, I've found that one of the larger Viewtainers, which is about 8" x 3", is an awesome mini-toolkit container that's easy to access and stash. It's amazing how many different useful (and in some cases, full-size) tools, you can fit into such a tiny container: screwdrivers, sockets, specialty bits, pliers, mini-saws, tire irons, flashlights, and on. I keep one in my car, one in my bike bag, and one in my study on the second floor so I don't have to run out to the garage every time I need a screwdriver.
