As a former Orthopedic nurse and Certified Emergency Room nurse, I have handled stuff similar to this a lot. In addition, I saw this very product when it was introduced to the public on the Shark Tank TV show. The product is strong and useful in certain situations. Just a word of caution for those of you that want to keep some of this in your tool box, even a slight hole in the wrapper will cause it to harden, and if you apply it to something and want to remove it later it must be sawn off.
