Length:: 1:28 MinsThey're not expensive, thick velcro ties, but they get the job done. I just want to neatly wrap the cords to all the gadgets I've obtained as of late.

The price was great for the amount you get, too.Pack contained:1 roll 25 grey1 roll 25 blackEach tie is on a roll of 25 ; the end of each tie is perforated so you can just tug and detatch it from the next tie on the roll
