These pads are nice and strong and well packaged. I was concerned they would come in a box that would quickly fall apart or not close. However, this box holds well closed and feels sturdy so I don't have to worry about these things accidentally flying through my shop. They are also coated with a thin layer of oil to prevent them from sticking together during transport in hot storage. Overall I am satisfied with this product and packaging and they have been very helpful for various projects.
