Each is a cute, rubber-like cable clasp, about one inch in diameter, with an adhesive back. You stick them to your desk, to the wall behind it, or even to other items on the desk, and it keeps one or more cables-depending on the thickness of each cable-from falling. The clip's "jaws" are sturdy enough to secure even the thickest FireWire cable, or several thin ones, but flexible enough that it's easy to get cables in and out of the clip when needed. They are also useful for routing cables to keep them out of sight and for storing earbuds when not in use. We also recommend them for keeping track of which identically-looking cable connects to which device.
