Quick Straps are the easiest of all leg straps to use, and are the most visible on the cow. The protruding end of the Quick Strap is like a 'flag' waving on the cow's leg. The Quick Strap is removed simply by pressing the release button! For added safety we recommend using Quick Straps on both legs of antibiotic treated cows. Quick Straps are not supplied pre-printed. Marking pens will give temporary marks suitable for short-term notices if required. Sold as each.
