Y-Tex blank sheep-goat ear tags use an advanced polyurethane formulation for a softer, more flexible tag. Ideal size for sheep and goats. Ear tag sets come with male and female tags. Patented Snap-Lok collar provides superior resistance to snagging and prevents male-female ear tag separation. Sheep and goat ear 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. Size 11/16” wide x 2-1/8” high.
