Ultra Retractable Cables
 

"People in general like things to be somewhat organized. Be it your house,
or the cabling on the computer, things definitely have their place. Now
your computer can look awesome on the inside, but the rats nest of cables
on the outside draw away the attention. Or you are someone on the go, and
need to carry the least amount of stuff possible. These are the markets
that the Ultra cables are aimed at.
