Clip-to-Clip Wire - 7 Inch / 18 cm

I was worried about the clips not holding, but the metal posts snap in firmly and the 7-inch length is perfect for my setup. Both wires came in the pack, so I had a spare right away.

These click right onto the metal posts and hold everything together with no wiggle. I was worried 7 inches would be short, but it's plenty to bridge two cubes with a little slack to spare.

The 7-inch length is exactly right for daisy-chaining cubes side by side without any slack hanging around. Clips snap firmly onto the metal posts and haven't popped off once.
