These are new in the packaging Vietnam War era elastic cotton bandages. These are original new old stock manufactured by Paulis Silk Company based out of Rhode Island. The packaging is in excellent shape and may still be Sterile after all this time in storage.

These rolls are approximately 3 inches by 5 and 1/2 yards according to the box.
In terms of practical use, this is excellent for filling out your little first aid pouch.
