Review on Nite Ize Gear Tie - Pack of 16 Assorted Sizes: A Versatile Organizational Solution by Matthew Sutton

These things go on the rubber bands on your hands. You also don't have to cut them to length like you do with velcro, but I still use the velcro type for cords, which are mostly kept. The small ones are perfect for frequently used charging cords, but they don't always fit everything, so the larger sizes come in handy. Try them as a set and like me, you'll probably end up buying more.
