They are very thin and made of nylon. They are flexible but break easily (even when placed on top of something) and cannot support weight. However as they served my purpose of putting a light chicken wire on the fence to prevent chipmunks from entering my yard I am giving them 3 stars which is probably more than they deserve. If I had bought them for any other reason e.g. B. cable management, to hold something, to support any weight, they wouldn't do their job, so I wouldn't be able to use all the extra features for something else.
