Y-Tex All-American ear tags use an advanced polyurethane formulation for a softer, more flexible tag. The long, ribbed neck prevents breakage and allows greater tag visibility. Flexible male button and patented Snap-Lok collar provide superior resistance to snagging and prevent tag-button separation. Y-Tex male buttons make a very small ear hole and have a longer shaft to provide greater air circulation around the incision, for rapid healing. Sanitary button tip does the piercing to prevent spreading infection between animals. Standard numbered tags are hot stamped with foil dye and guaranteed legible for four years. Y-Tex medium (3-star) ear tags are excellent for cow and calf use.
