This is a Doctor's grade elastic bandage one time use. I need a bandage that will take the test of time. I wrap my leg every day to push the blood back up to my heart to prevent sores. I bought a box of 50 thinking 4.5 yards stretched x 4" would work. Not so right from the start it started to pull apart. This is a one time use bandage it may be good for a doctor's office but not what I need. Needless to say a wast of my money. I do not blame the seller for my lack of knowledge.
