The most advanced livestock ear tags in the world! Easier to put in! No more torn ears! Superior readability! Unique self-piercing tip! Superior retention! How many ear tags have you lost in the last year? Well, if you’ve lost even one, you’re not using Z™ tags. It takes a lot to lose a Z™ tag. The unique, highly flexible, one-piece design won’t break, pull out, or even snag. The self-cutting tip makes a small, surgically precise hole that hugs the neck of the tag so that it heals quickly to prevent infection. The applicator (not included, sold separately - C19312N) features a pivoting pin that makes loading tags easier - and prevents torn ears. Hot stamp print is bold and easy to read. So Z™ tags stay easy to read - and stay IN - for the life of the animal. Guaranteed.NOTE: Please allow extra delivery time for tags numbered over 100. Personalized tags cannot be returned for credit. These numbered tags are packaged in 25 sequential numbers and can only be ordered as such.
