A quick and easy method for temporarily marking the legs of dry, treated, or special cows, popular Flagbands have countless other uses around the farm and home. Now available in purple. Our Flagbands are made out of tough nylon hook and loop fabric, power welded for long life and durability. Simply press the ends together--once on, they stay on until you grasp and pull to remove. The material is washable, reusable, and durable, and can be written on with a felt-tip pen.
