Each roll of our Roll Cotton - Standard Grade is non-sterile and weighs 1 pound and has the approx. dimensions of 12 feet in length, 12 inches in width and is 3/8" in thickness. The cotton fiber of this grade is not quite as long as our Premium Grade but still forms great cotton tipped applicators or can be used to form a cotton ball to clean larger areas without leaving fibers behind. These cotton rolls are sold by the each.
