A unique, two-part design that attaches to and stays with a USB charging cord during use. Just lay the cord in the center channel, reattach the lid, and wrap the cord's end around the center of the wrap to shorten to the desired length. The rubber sides neatly keep the cord inside, intact and protected. Or completely wrap the cord to take the USB with you. Included ID strip to keep organizing easy. Assorted accent colors include: Black, Blue, Emerald, and Pink.
