All American ear tags use an advanced polyurethane formulation for a softer, more flexible tag. Special ultraviolet light inhibitors stop fading for superior hot stamped or inked imprint life. The long, ribbed neck prevents breakage and allows greater tag visibility. Sloped tag shoulders combined with Y-Tex's flexible button and patented Snap-Lok collar provide superior resistance to snagging and prevents tag-button separation. Buttons are included.
