These hold cables and other cords great! I have to say the picture was a little misleading because it looks like plastic when it’s really cloth. You get two organizer sleeves. One is a width of 6 inches and the other is a width of 4 inches. They are both 60 inches long. You are able to cut them to your desired length. They are reversible, one side is white and one side is black. These sleeves are made from highly durable flexible neoprene. They are very well made and the quality is great. You simply wrap the sleeve around the cords and then secure it with the velcro. The velcro is high quality as well.
