These Cable Caps by Quirky are part USB cap and part cord management tool. The top of each cap is made to cover any open USB plug, and its "body" is made of flexible plastic to wrap around the cord, keeping it tangle-free.
Designed to protect your USB cables, this cool tool allows you to easily distinguish cords from one another and keep them from tangling. Cable Caps come in six designs and are sold in packs of three for $8. I love the idea, but the design may be a little too cartoonish for my taste. What do you think?
