(Allflex) Allflex Tamperproof hog ear tags offer advanced security for your livestock identification and management program. When Allflex Tamperproof hog ear tags are applied, the self-piercing tip of the male panel tag is locked tightly into the Tamperproof small female button. Longer male stem allows for higher tag placement in the ear. Hog ear tags swivel to prevent snagging, but cannot be removed without being destroyed. Ideal for official certification or registration programs, or to provide added security and peace of mind. Allflex Tamperproof hog tags are made from polyurethane, making them completely waterproof, tough, durable and snag proof. Allflex Tamperproof hog tags are shipped with Tamperproof small female buttons. Numbered ear tags are printed in high contrast Allflex Laser-Ink Marking. Underneath a dark ink overlay is the matching laser number etched permanently into the surface of the tag. Laser engraved printing is guaranteed not to fade. Numbered tags are available in packages of 25 consecutive (sequential) numbers. Specify the number series that you wish to order when finalizing your order in the "special instructions" field. Use Allflex Universal Total Tagger or Global Retract-O-Matic to apply tags. 1-1/2" high x 2-1/4" wide. 31/32 shaft.
