(Y-Tex) Y-Tex All-American swine ear tags use an advanced polyurethane formulation for a softer, more flexible tag. Patented Snap-Lok collar provides superior resistance to snagging and prevents tag-button separation. Y-Tex SwineStar male tags make a very small ear hole and have a longer shaft to provide greater air circulation around the incision, for rapid healing. Sanitary 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 SwineStar tags are packaged with round female buttons. 1-1/2" high x 2" wide.
