Y-Tex All-American ear tags are made from 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 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. Y-Tex medium (3-star) ear tags are excellent for cow and calf use. The 3-star medium two-piece tag can be used on cows or calves. These tags can be applied with the Ultra Tagger Plus or Ultra Tagger Compact Applicator. Contains: 25 back buttons and 25 ear tags.
