The thing to do, is keep one of each color bungee cord and then if you ever want a whole unit, you could re-attach the desired clip to the proper color cord. Most of the cords seem identical and are made in China.

Incidentally, 4 collectors have already shown interest in a RR. Only need about 2 more to make it a reality.

Now we need to come up with a name to call these "thingies"...
Curly-cord clips?
Bungee snaps?
Slot card connectors?

What do they call them in the business?
